You should be able to find these files via Terminal.
- Open Terminal application
- Type
cd
(that's three characters, the last one is a space) and then drag the folder containing the photos from Finder into the Terminal window. This should add the full path.
- Press Enter
- Type
ls -ltc | head -250
to see the 250 most recently renamed files.
As long as the filenames are somehow sensible and don't contain line breaks or similar,
cd path/to/folder/with/pictures
mkdir -p ../renamed_pictures
ls -tc | head -250 | while read line; mv "$line" ../renamed_pictures/; done
will move them to a new directory at the same place as the pictures
directory. Replace mv
with ln
if you just want to link them there (create new directory entries pointing to the same file) and also keep them in the original directory.
