My goal was to flatten a complex directory. I went to the complex directory and searched for all files with * in the search box. I sorted the results by file type and selected all the files -- in other words, I excluded the folder names. I should have done a COPY at this point -- but I did a CUT (control x) and then pasted into the new target (flat) directory. Turns out there were many files with the same names. Accidentally I said "yes" to the replace files with same name question ("Would you like to replace the existing file").
Is there a way to recover the missing files?
