I’ve found a way to remove the annoying thumbs file that prevents me from deleting folders. Currently, I go into a folder, shift-click “run power shell window here and then type:

rm thumbs.db -force

However, that only works when in one folder where it’s located. If I go up to a parent folder and try that with “-recurse” anywhere in that line, it won’t work. So what other way can I delete them in all the subfolders without manually going into each folder?
