DirMaster v2.2/Style screenshot

DirMaster v3.0 should be released within 1-2 weeks!

DirMaster is a Windows-based GUI tool useful for the management of common (and uncommon) emulator formats (such as .d64, .d81, .d2m, etc) as well as native archival formats (such as .arc, .sda, .lnx, etc). DirMaster differentiates from and surpasses competing GUI tools with its focus on usability - a perfect blend of familiar appearance (e.g. natural looking disk image contents using the CBM character set) with modern GUI functionality (e.g. drag and drop, working with multiple disk images at once).


  • disk image support: .d64, .d71, .d81, .d80, .d82, .d2m .dhd, .dnp, .dfi, .g64 (read only)
  • file support: .prg/.p00, .seq/.s00, .usr/.u00, .rel/.r00, .t64
  • archive support: .arc, .sda, .lnx, .ark, .cvt, .sfx, .wr3, zip/4 (1!..., 2!..., etc)
  • integrated with Explorer via file associations/icons
  • fully working drag and drop:
    • copy one or more files from one image to another
    • copy files between different image formats (e.g. d64 to d81, dfi to d71, etc)
    • move/reorder files on the same disk by dragging them
    • drag and drop files from disk images to the OS file system
    • drag and drop files from the file system onto disk images
  • open literally hundreds of images at the same time
  • sub-directory support for relevant formats like d81 and d2m
  • great support for GEOS files
  • invoke your favorite emulator (up to eight slots) from within DirMaster to run a file
  • recursive find: search your disk image collection, fast (~125 images per second, ~7.5k per minute), with * and ? wildcards
  • save disk images as a .txt, .csv (with optional MD5 hash per file), or .bmp
  • batch processing: recursively create .txt, .csv, and .bmp or extract to prg/seq files
  • most functions activated by keyboard equivalents, including file reordering and filename editing
  • all the usual directory editing capabilities like sorting, block size change/correction, file type change, lock, splat, etc...
  • multi-level undo for most operations
  • user friendly visual BAM mode with full featured track/sector view/edit (hex and PETSCII); BAM mode supports standard error-track extensions
  • decompress archives directly from open disk images with one key click
  • maintain your own favorite 'separators': drag and drop them onto your disk image
  • working just fine under WINE for Linux/FreeBSD/Solaris freaks
