There was a question about how to restore files in Windows…
If the file is in the Recycle Bin, it can be easily restored from there:
open the Recycle Bin…
select the file(s) to restore…
restore the file(s)…
and, when you are done, close the Recycle Bin window.
I found a (Windows 2000) description at http://www.microsoft.com/windows/windows2000/en/advanced/help/recycle_bin.htm
If you have the Business, Enterprise, or Ultimate versions of Windows Vista you can try to restore a previous version…or shadow copy…of the file.
“Previous versions are either backup copies—copies of files and folders that you back up by using the Back Up Files wizard, or shadow copies—copies of files and folders that Windows automatically saves as part of a restore point….
“Right-click the file or folder, and then click Restore previous versions…”
If the file was “deleted” from the hard drive, you can consider software that will try to help you recover the file. There’s a lot of these products available…at the moment, I don’t have any that I can recommend over others.
