Thanks for response. The last version of the program is from 1991, I assume that there will be no updates in the near future, so I will add a comment in FD help that it may cause problems on newer systems.

At the moment I do not remember OTHER apps with the same bug, but there are still a lot of programs that support FAT16 only and should be improved for FAT32 usage, e.g. chkdsk and scandisk (scandisk has only restricted FAT32 support).
