Ever had such an annoying message given by Windows?
It has many other flavors:
Cannot delete file: Access is denied
There has been a sharing violation.
The source or destination file may be in use.
The file is in use by another program or user.
Make sure the disk is not full or write-protected and that the file is
not currently in use.
Long Path Tool is the solution!
