The software contains a protection mechanism that restricts access to a long filename on a Windows operating system, but the software does not properly restrict access to the equivalent short "8.3" filename.

On later Windows operating systems, a file can have a "long name" and a short name that is compatible with older Windows file systems, with up to 8 characters in the filename and 3 characters for the extension. These "8.3" filenames, therefore, act as an alternate name for files with long names, so they are useful pathname equivalence manipulations.
