Hi Ayushrajput,
The “$RECYCLE.BIN” file is important because it gives you the opportunity to undelete a file from the recycle bin.****Each hard disk contains a hidden folder named $Recycle.bin. This folder contains files deleted in Windows Explorer or My Computer, or in Windows- based programs.
Note: Do not delete the hidden files. When you delete a file, the complete path and file name is stored in a hidden file inside the $Recycle.bin folder.
Windows 7 creates a fresh $Recycle.bin folder automatically after you reset it.
IMPORTANT: The following procedure permanently deletes all files and folders which are already in the Recycle Bin (from all user accounts in the system) and cannot be recovered.
a. Open an elevated Command Prompt window.
b. To open an elevated Command Prompt click on Start and click on All Programs.
c. Click on Accessories
d. Right-click on Command Prompt and then click on Run as administrator.
e. Type the following command and press ENTER:
rd /s /q C:$Recycle.bin ****(This clears out the $Recycle.bin folder from the C:\ partition. Instead of C: choose the hard disk partition in your system.)
f. Type exit to close the Command Prompt window.
Hope this information helps. If you need any further assistance or information about Windows, I will be glad to help you.
