On my old pc where everything else is working just fine, no problems, no viruses: I had a text file and read it this morning. Later I used search (above the start button) to find it again. Right-clicking properties, I found the file was read-only. I tried to copy the file from the search list but Windows 7 Pro wouldn't let me. It only created a shortcut in the folder I wanted to copy to. Deleted the shortcut.
Still later that file didn't show up using the same search. Searched in Windows Explorer. Nope. Thought a pointer might've gotten messed up and tried a Restore Point (to yesterday). Read here that RP only deals w/system files (which is why your data files are left alone). Don't understand how the original file was 'lost' but wondering if I run Scandisk if that might help.
Not a big deal, the data can be re-created basically. But I'd rather have the original back.
As always, any feedback would be appreciated : ),
