|The 'Recent' folder contains only 'shortcuts' to files, not the |
actual files themselves. The shortcuts remain even when the
actual files have gone.
I'm always stressing to people to keep backup copies of every
file they create or download, in case the originals get zapped.
All I can suggest is you do a 'search' if you can remember the
filenames or part of the filenames. Or you can use a wildcard
if you know what the filename extension is.
For example, if it's a Word document, open the search box
and type *.doc, choosing the whole of your 'C' drive as the place to search.
Also have a look in the Recycle Bin, though it's unlikely they'll be in there if they weren't deleted manually.
It's possible something has deleted them but they are still on the hard disk, or at least some of them might be if you haven't overwritten them with other files or program installs. If they exist you need to 'undelete' them with recovery software. Try this:
Remember, for the best chance of recovery don't install anything else or perform a defrag which could overwrite what remains of the lost files. Some of them may be only partially recoverable if they've already been partly overwritten by other data.
It really depends on how long it is since they went missing and how much you've used your PC since then. I hope you get them back, but do please keep regular backups on an external drive or optical discs in future!
