I ran "cmd" and in DOS i went to the directory "1" that was holding the problem-folder and then i typed "dir/x" to get the 8.3 format of the folder.. and tried "del <foldername>" and it didn't work.. Then i tried the rename command..
"Ren <8.3foldername> <new shorter foldername>" ... it actually let me rename it and then i closed DOS and went back to explorer and now it's acting like a regular folder that can be deleted or whatever again. "
There are more options in that posting but this is the only one that worked for me...
Sadly, this is apparently still a problem in Windows 8.1. I had a folder copied from a Mac that I couldn't delete, with a name that ended in a period. I couldn't rename move or delete it any other way, but this part of the solution finally worked. In the
end, I had to repeat the steps 3 times, in order to get rid of the two folder levels above. Thanks, AJ88CAB!
Just to clarify, using dir/x to expose the old DOS-style short filenames allowed me to work with the locked, empty folders. The system said an open program was using them, but I never figured out which one.
