"old" ??? I use ZIP-CODE to this day. Someone recoded it around 1992
(search for ESH-ZIP) ESH has better pack results but pack time is increased.
I think a better storage method these days is a D64 that has been PKZIPed
as Pasi's GUNZIP.C64 will PKUNZIP the D64 onto a 1541 disk all from a stock
c64. Still, D64 files (PKZIPed or not) are impractical without a PC to
sort images and arrange for transfer/storage to the c64.
ZIP-CODE uses RLE packing, fast but poor compression results...

Cool! Where can I find the version of GUNZIP.C64 that does that? I
always thought we need a utility to essentialy unzip a PKzip 2.04g
file and pipe it into a D64 disolver then directly onto a 1541 disk
all from a stock C64. As you know, a D64 image file will not fit on a
standard 1541 disk, so a CBM user must have a 1571 or larger drive to
handle a D64 file, instead of just two 1541 drives.

Yes, we once did need to do that. Now you can perform the
decompression and image write on one go. The best part is
that because of compression, the D64.gz or D64.zip DOES
fit into a 1541 disk and you only need one 154x/7x drive!

Nice coding there mate. Glad you understand LZH commpression cause
I sure as heck don't. On the i/o drive select prompt you have
"8-9,0-7" does this mean that I can't read a file from 8,20 ?
(ie. drive 8, partition 20) I haven't tried yet...

"It's called ZipCode. In case you have a PC, the nowadays-standard
PC-to-C64 data transfer program, Star Commander, http://sta.c64.org/,
can assemble those 4 files on its own in the PC before transfering the
whole disk to the 1541. In fact ZipCode has a problem as it uses a
fast but pretty unreliable fastloader code.".
There are advantages (and disadvantages) to using the SPYNE format in place
of ZipCode, for transferring a 1541 disk in the form of a file (or files). In
both cases, the four ZipCode files (or one SPYNE file) may be a little too
large for a 1541 disk. But a SPYNE file is self-extracting; no other program
is needed. And the user may opt for a destructive extraction; the same disk is
used and no free blocks are required.
And if a SPYNE file is downloaded using a PC, "64COPY" (by Peter Schepers)
will extract the files.

If you see a telephone keypad above, you're probably using a Commodore 64.
The numbers mean drives 8-17. Currently gunzip.c64 is a little
hostile to REU/Ramdisk and probably HD also, because I don't
have those peripherals. I'm trying to change this from hostile
to just "not special support" for the next version.

Thanks, I'm surprised I missed it earlier. I have not tried it yet,
but I assume that it works as described. This is a better utility
than I expected wtih the sigle drive capability. There is one
remaining difficulty with the D64 format. You still need a 1541 or
1571 drive and 5.25" floppy. Many D64 disk images contain only
standard CBM files, It would be nice to be able to extract the files
directly to a 1581 drive. All my 1541 drives are in storage. I do
have a 128DCR at my desk, but I always have a hard time finding a
blank 5.25" floppy.
