Filename too long

While recovering data from an old NAS, I encounter a folder that would not delete after being restored on a USB Drive.  The error Windows was throwing was:

The filename would be too long for the destination folder.   You can shorten the file name and try again...

After a bit of research, the following workaround was used to successfully delete the folder.

• open a command prompt
• cd into the nested directory folder (i went about half way down)
• subst m: .
• j:
• rmdir /s remaining_folder_name
• c:
• subst /d m:

This effectively assigns part of the large nested directory folder to the m: drive, and allows you to switch to that drive and delete the remaining nested folder.
