Using my pc to copy across adf disks to my amiga using crossdos. Now some disks will not compact to the 720k limit. I read that you split the files but how? Using an amiga 1200 with normal case and a jaws 63030@40 and 4mb ram. Do not want to use a null modem cable and that takes frorever!

This method is still time consuming but it works for me. Get a copy of transdisk and a pc file splitter program - I've got a nice simple one that I could email to you. You'll also have to use the Amiga shell program called join.
Yeah, before I resorted to this multiple disk swapping method I was trying to compress adfs with LHA - on an A600 with 2 megs. Never again...
:-)

I don't know if this is what you need or not.
step one involves aquiring an archive util that will uncompress zip or rar on the amiga platform and install it.
step two is to compress the adf in zip or rar and place the file on a PC 720K floppy and move it to the amiga on 720K PC floppy and read it with MSH or CrossDOS.
step three is to extract the adf to ramdisk or some other location.
step four is to aquire Transdisk available on AmigaForever or Aminet.net and follow the directions for writing the ADF to disk.

hmm... after reading the post again I see that I ddint answer your question.
However, there was some information that was actually useful.
Use Transdisk. The command to copy to two disks looks something like this:
transdisk >RAM:df0a.adf -s 0 -e 39
this will write half of the adf to a PC formatted floppy in drive df0.
do it again for the next half on another PC formatted disk:
transdisk >RAM:df0a.adf -s 40 -e 79
After copying both files to PC use this command to combine them on your PC:
copy /b df0a.adf+df0b.adf df0.adf
That makes a file called df0.adf and is the original adf file on the amiga.

well i havent posted anything in ages so here goes:
you could use a file splitting utility. i have, it works, but it's a pain.
there's a program called Tequilla that should do the job. But it comes with a file you need to have on your Amiga so you'll need to get it on there with a 720kb formatted disk. the text file should explain everything well enough.
good luck.

Using LHA has always worked for me! I compressed the ADFs on the PC side and put the files onto dd floppies. These could be read on the miggy with crossdos - I used LHA on that end to extract them to RAM and one of the ADF-to-disk progs to put this onto a blank disk.
This was all done on a stock 2Mb A1200 with no HDD. With this, I could get all the stuff from my PC to the Amiga with just an ancient WB1.3 floppy and a copy of CrossDoss from the 8th Amiga Format collection (circa late '80s)!.
But not everyone'll like it :-)

You can also gzip ADF file -> to get ADZ which usually takes less space than 720 kb. TransADF handles ADZ quite well even on A500, so on A1200 there should be no prob.
For spliting files use google -> "splitz joinz" should get you some clues.

Im not sure why you dont want to use a null modem cable as opposed to a floppy because of speed? compressing a file, copying it to disk, moving it to amiga then uncompressing is far slower than a direct copy via a null modem serial cable!
If you change your mind ive put up a "how to" for making a serial cable on Amiga Monkey How To - null modem cable (http://www.amigamonkey.com/ami/howto/details.jsp?element_id=7)

Read on a website that it takes over 30 mins to send a disk using a null modem cable. Prove me wrong?

have you actually done this? Have I set mine up wrong? I've never timed it but null modem takes forever! I could copy 2 or 3 disks in the time it takes to download a half meg file on my A1200.

Install JoinSplitter (http://aminet.net/util/misc/JoinSplitter.lha) on the Amiga, Install HJSplit (http://freebyte.swmirror.com/hjsplit.zip) on the PC, use HJSplit to split the files into 700 KB chunks, copy each chunk onto a seperate floppy (or the same floppy progressively), mount PC0: on the Amiga, copy chunks onto the Amiga HD (or RAM if you have enough) and use JoinSplitter to join the chunks.

You can use 'SPLOINER' program under PC and under Amiga.
It's a command-line program like lha.
Search it in internet!
