pro_opt - Optimize an Apple II ProDOS disk image file
pro_opt IMAGE-FILE OUTPUT-FILE
pro_opt eliminates wasted space from a disk image file containing an Apple II ProDOS volume. It does this by creating a new disk image file and copying all files from the old image to the new one. Any un-allocated blocks are eliminated from the new image file.
Note that some emulators cannot deal with image files that are smaller than their nominal size. That is, they expect a 280 block disk image file to be 143,360 bytes long. pro_opt should not be used with such emulators.
pro_opt requires the modules AppleII::ProDOS and AppleII::Disk, which are included with LibA2.
There are no known bugs, but you should keep a copy of your old image file until you're sure the optimized image file works properly.
