LoveLearn I've used an app called DoubleKiller that compares by any or all of the following four criteria: 1) Name 2) Date 3) Size 4) CRC-32 checksum IIRC, you can also set size thresholds (> or <) and file attribute filters. AFAIK it's freeware, also. Received on 2003-12-08 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
