How to delete a Windows file when you have the “the file name is too long” problem”, and everything on your system is refusing to even allow a re-name of the file.
On desktop PCs the common WinRar .rar file-compression software can handle such extra-extra-long names, and can re-name them in its file-system viewer. Simply use WinRar as if it were a Windows file explorer, find the file, and rename to something shorter. Then delete it using your usual Windows File Explorer etc. WinRar is free for a 40-day trial.
