* If the disk image file extension is ".dmg" this is for Mac OS X based computers, not classic Mac OS.
* If you have a disk image which DiskCopy will not read, the file's owner and type codes may not be correct. This may happen to files copied from other platforms without being compressed inside a .bin/.sit/.hqx container. ResEdit can be used to set these attributes (match them with a working disk image file).
