blimey! reading that old thread really brought back some memories.. I cannot believe I wrote those utils that long ago!
Unfortunately I lost 99% of all my Amiga related stuff due to a hard drive crash a few years ago.. and kind of gave up and just lurked around this board like an old ghost never really posting much.
Last thing I remember doing was that I was able to extract files from the adf image and save them in windows then add files back into the adf but can never remember if it worked correctly (the disk still appeared valid in my program but I never tried using any of the disks I modified with Winuae)
