You can restore the files and folders that you had deleted from My Documents with the help of the Recycle Bin.
To restore a file, follow these steps:
To go to the Recycle Bin click on the Recycle Bin button on top of the My Documents page.
On this page you will see all the files and folders that you had previously deleted from My Documents.
Beside each file or folder you will see two links Restore (which is used to restore the file to its original place from the Recycle Bin) and Purge (which is used to remove the file permanently from the Recycle Bin).
The Empty Recycle Bin on top of the page is used to permanently remove all the content of the Recycle Bin.
Note: Once a file is purged or removed from the Recycle Bin it cannot be recovered.
