DLGfdf (no it's NOT a typo :) helps you with the horrible task of finding
double files (or files with multiple versions) in your DLG-Pro BBS.  It
scans all your file area's and compares the first x (adjustable) chars of
the filenames and produces a list of double files that can be saved.

v2.1: Cosmetic changes.  Scanning of BBS can now be interrupted.  File lists
      can be now be appended to eachother (or to other files).  Added
      possibility to scan a device (or directory) for files and have them
      compared with files in your BBS.
