I have a large pictures folder, most of then "bulk" downloaded using Hitomi Downloader, DownThemAll and similar. Yesterdary I ran a Powershell command I always use to rename the last downloaded files and found the folder empty (aside the renamed files). I'm not sure how and when the files and subfolders dissapeared, but Windows shows the folder as empty, 0 bytes size. It must have happend at most one week ago. I suspected of the Powershell command, the Hitomi task cleaning process or a failed undesired cut operation.
I have the hidden files visible (File Options > View > Hidden files) and rebuilt Windows file index (Indexing Options > Advanced Options > Rebuild). I tried several recovery tools like Recuva, Disk Drill and Do Your Data Recovery, but none of those found deleted files in that folder. I've also tried to search some of the files and folders in the whole disk but found nothing.
The files must be somehow hidden there because the deletion or moving of such a large folder (several GB) would have been noticeable with a progress modal and because the drive available space don't seem to have changed.
What else could I do? Is there another tool to list "hidden" files?
Note: Powershell rename command I used. I tested it later in another folder without errors.
Get-ChildItem *.* | select FullName, Extension, @{name='md5'; expression={(Get-FileHash $_ -Algorithm md5).Hash}} | foreach {Rename-Item $_.FullName -NewName "$($_.md5)$($_.extension)"}
