No idea where it came from but I have a folder with about 50 sub-folders - each one called: '-Test', each one is empty.
It will not delete - "The source file name's are larger than is supported by the file system"
I've tried all of the suggestions and many more I've found on the net to no avail.
I've laboriously renamed each of them to a single digit but the problem is not solved. An odd thing here: The deepest folder has no option to rename via the right-click menu. Also, when renaming folders a few levels above the deepest folder another sub-folder gets added (called: "-Test") to the bottom!
I've tried mapping a drive to the deepest file - cures nothing.
I cannot remove or delete the problem folder via the Command Prompt or Robocopy.
I've run chkdsk - no problems but the message: "Windows may not detect all cycles on your volume because the directory structure is too deep" appears.
I've tried moving parts of the problem folder to other areas and then deleting them. That works but there's always just one section left which then mysteriously grows back to 47 sub-folders.
I've run full malware and virus checks to no avail.
The deepest folder is odd in that the right-click menu is missing quite a few entries such as Properties, New, Delete, Rename, Cut, Copy, Send To, etc.
I've tried adding the whole thing to a zipped archive - no go.
Anyone got any further ideas?
