The latest update to DirMaster, v3.1.3, has been released. There are no new features in this release, only bug fixes.
Issues reported by users that were resolved in v3.1.3:
- Windows XP compatibility restored in 3.1.3  (Luca/FIRE + others)
- Extending a d64 from 35 to 40 tracks, track 35 is destroyed (stephan-andres)
- cvt file copy would result in failure to validate the disk in GEOS (scott.hutter)
Thanks to all who made an effort to submit bug reports. If you sent a bug report and don’t see it addressed here, don’t worry, it’s in the queue.
Other issues resolved in v3.1.3:
- “Mark disk for GEOS” incorrectly writes the border sector 
- New d64 images are more accurately matching the 1541 formatted content (open1,8,15,”n0:” style) 
- BAM view could cause a crash when viewing truncated disk images, this should be less likely now 
- An error message would sometimes be shown when quitting DirMaster after launching a disk image in an emulator 
DirMaster is a Windows-based GUI application designed to help Commodore enthusiasts explore and manage their disk image collections.
DirMaster supports common (and uncommon) emulator disk image formats (such as .d64, .d81, .d2m, etc), almost every native Commodore archival format (such as .arc, .sda, .lnx, etc), and many native graphic formats (such as koala, doodle, amica, etc).
DirMaster was designed to give users a perfect blend of familiar appearance (e.g. natural looking disk image contents using the PETSCII character set) and modern GUI functionality (e.g. drag and drop, opening multiple disk images at once).
