Your version of [iDSK] must be updated. Please download the current version http://sid.cpc.free.fr/iDSK.0.13-src.tgz.
What's new : Amstrad Image Floppy disk manager. Manage your floppy image disk .dsk as you want. A lot of options available. Available as source, compile it on all Unix clones platforms. Thank you to Pulko to correct some bugs.
