     As far as I know, ADT can use only size to determine whether or not a disk
image (.dsk) file is acceptable. The standard size of a .dsk file is 143,360
bytes. This is exactly the number of data bytes on a 35-track, 16-sector 5.25"
diskette.

     Every once in a while you will find a .dsk file which is a few bytes off in
size. At least a few emulators (including AppleWin) will accept such .dsk files
without complaint. ADT seems to require that the file be exactly 143,360 bytes in
length. If it isn't, you get the "is not a 140k image" error message.

     One possible cure is to format a Dsk (or delete all files from a copy of an
existing 143,360-byte Dsk) and copy the files from the weird-length Dsk.
