     Creating 5.25" disk image (.dsk) files or converting them back to
diskette are tasks usually handled on an Apple II. The information below
should help.

016- What are DSK "disk image" files and how do I use them?

     A "disk image" is a file containing everything on the diskette--
i.e. Catalog tracks, files, DOS (if present) etc.. Usually, they are
images of Apple 5.25" game, utility, etc. diskettes. A standard 5.25"
disk image file is 143,360 bytes in length.

     DSK files are disk image files used by emulators like AppleWin to
run A2 wares on the PC or Mac. Emulators treat DSK files like diskettes.

     DSK files are also a handy way to archive DOS 3.3 disks on hard
disk and to maintain old DOS 3.3 wares on Apple II ftp sites. On Ftp
sites, DSK files are usually in a ZIPped form to conserve space. For
example, on the Asimov site, narfgames.dsk.gz is a DSK file of the
narfgames disk which has been g-zip compressed. On a PC, WinZIP will
unZIP g-zipped DSK files into uncompressed form.

     On an Apple II, a DSK file can be converted to actual 5.25"
diskette form using DSK2FILE or (GS-only) ASIMOV. Most 5.25" DSK (.DSK
and .DO) files are of a DOS 3.3 or some related DOS disk. The target
diskette should be formatted for DOS 3.3. and you should use the default
DSK2FILE or ASIMOV "DOS 3.3 Order" setting. Copy II Plus can do the DOS
3.3 format. (If a disk image file has a .PO suffix, use a diskette
formatted for ProDOS and the DSK2FILE or ASIMOV "ProDOS Order" setting.)

     An alternative way to do a DOS 3.3 format is to boot a DOS 3.3
diskette, get to the usual BASIC prompt, swap your target diskette into
the drive, and do an INIT HELLO. (Prontodos or EsDOS-II are speeded
versions of DOS and can also be used to do the INIT.) INIT, of course,
does a bit more than a Copy II Plus format; but, the stuff added gets
over-written. Both ways to do the format have been tested and work fine
for preparing a target diskette. If you want to also use the back of the
diskette as a target, then, it will need to be formatted, as well.



     Here is a quickie step-by-step guide for getting a 5.25" DSK disk
image file into useable form:


1. Download the file in binary mode from an ftp archive site via ftp://
...

2. If file length is not 143,360, use WinZIP or equivalent to unZip it.

3. Transfer the DSK file to your GS via Mac diskette or a NULL modem
transfer. One way or another, the file needs to end up on a ProDOS
diskette or ProDOS hard disk volume on the GS.

4. The vast majority of DSK files are images of DOS 3.3 diskettes.
Unless you have good reason to believe the DSK is an image of a ProDOS
diskette, format or INIT a 5.25" diskette for DOS 3.3. (If the DSK file
has a .PO suffix or if you have good reason to believe the DSK is an
image of a ProDOS diskette, format the target diskette for ProDOS.)

If you are using DSK2FILE, now is a good time to jot down the complete
path name of the DSK file (e.g. /RAM5/NARFGAMES.DSK ) because DSK2FILE
will ask you to type it in.

5. Insert the formatted target diskette into 5.25" Drive 1 (Slot 6).

6. Start DSK2FILE or ASIMOV. Normally, you will accept the defaults. (If
the DSK is a ProDOS image, select "ProDOS Order".)  

7. Select the "Image file ---> Diskette" option, follow prompts, and you
should end up with a good diskette.


     You can, also, use DSK2FILE or ASIMOV to create DSK files from
unprotected 5.25" diskettes. 

     In some versions of Copy II+ (up to around version 7.x) the
COPY--DISK function can create disk image files and convert them back to
diskette. Copy II+ disk image files are not compatible with those
created by DSK2FILE and ASIMOV; and, they do not work with popular
emulators.
