Laptop decided to reinstall Win 7, programs still seem to be there, but files have gone, mostly Excel and Word, I installed and ran Recuva, (free version) it has found loads of files, quite a lot are not overwritten and come up about the right size in the list of files available for recovery. When I check the files to recover, all seems good, but all that is actually in the folder is a shortcut to the file, not the actual data.
the re-installation of Windows 7 should have put all your personal files in the Windows.old folder within the Users folder - like they were before the install.
so look there.
because your programs are still there, it didn't do a fresh install or factory reset install, so you should be good.
a bigger question is, WHY did that happen? (that sort of thing doesn't just happen out of the blue)
as to why - a couple of years ago laptop did a Win 10 upgrade, crashed a few days later, got it back up onto Win 7, and has been a bit dodgy ever since, routinely starting up with
'preparing computer for first use'
message, which went away after a couple of mins and reboot continued normally.
The other night on switch on it came up with 'reinstalling windows'
now I can see some - if not all the programs, but all files have gone, iTunes shortcut is still on the desktop, but is looking to reinstall
so under C:\ drive, you see no windows.old folder?
it shouldn't need it, but check your folder options allow you to see hidden & system files.
let me guess, you have no backups either? <img alt=":)" data-emoticon="" height="20" src="<fileStore.core_Emoticons>/emoticons/default_smile.png" srcset="<fileStore.core_Emoticons>/emoticons/smile@2x.png 2x" title=":)" width="20"></p>
File's data not on disk means that the cluster addresses are not valid, they are probably set to 0xffff. There's no point trying to follow these addresses.
You may find your files with a deep scan, if, at the end of the scan, you filter for file type and date, size etc. But this is a long job, and if you find a file only the first extent will be recoverable without professional help.
