Secretly Hide Any File Inside JPG Image File
Few months ago , USA Today story claimed that al-Qaeda operatives were sending out encrypted messages by hiding them inside digital photographs [jpg files] on eBay.
While the claim was never proved, it is very easy to hide [or embed] any other file[s] inside a JPEG image. You can place video clips, pdf, mp3, Office documents, zipped files, webpage or any other file format inside a JPEG image.
And when a suspecting user [read CIA, FBI] tries to open that jpeg file [with concealed information] in either a photo editing software or as a thumbnail inside Windows Explorer, it would be tough to make out if this camouflaged jpg file is different from any standard jpg image.
Let's say you want to hide a confidential PDF document from the tax investigation officers. What you can do is convert that file into a regular jpg image so even if anyone double-clicks this file, all he will see is a preview of the image and nothing else. And when you want to work on the actual PDF, just rename the extension from jpg to pdf.
Here's the full trick:
Step 1: You will need two files - the file you want to hide and one jpg image - it can be of any size or dimensions. [If you want to hide multiple files in one jpeg image, just zip them into one file]
Step 2: Copy the above two files to the C: folder and open the command prompt window.
Step 3: Move to the c: root by typing cd \ [if the files are in another folder, you'll have to change the prompt to that folder]
Step 4: The most important step - type the following command:
copy /b myimage.jpg + filetohide.pdf my_new_image.jpg
To recover the original PDF file, just rename my_new_image.jpg to filename.pdf.
Here we illustrated with an pdf file as that works with simple renaming. If you want to apply this technique to other file formats like XLS, DOC, PPT, AVI, WMV, WAV, SWF, etc, you may have to first compress them in RAR format before executing the copy /b DOS command.
To restore the original file, rename the .jpg file to .rar and extract it using 7-zip or Winrar.

5 ways to speed up your PC
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 2 (SP2) and Windows Vista to more efficiently maintain your computer and safeguard your privacy when you're online.
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.
3. Clear the check boxes for files that you don't want to delete, and then click OK.
4. 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.
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.
2.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.
3.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.
4.To display detailed information about the defragmented disk or partition, click View Report.
5.To close the View Report dialog box, click Close.
6.To close the Disk Defragmenter utility, click the Close button on the title bar of the window.
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.
7.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.
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.
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.
