A600

amiga disk files are 880ks. you need to compress them before writing to floppy.

cover the empty hole on a 1.44 floppy with a sticker (not the write protection hole). format the disk with the command

format /T:80 /N:9 a:

on your windows. get lha from aminet. get adf2disk from aminet. extract these on your pc and put them into your floppy. get a adf and compress it with lha. put it into floppy. now boot workbench and put your floppy into your a600. put the lha somewhere on your path (usually, workbench:c). extract the adf file to ram: (well, anywhere else is also ok.). put a formatted floppy into drive. write the adf to disk with the adf2disk command.

when you get tired with all compressing and stuff, get yourself one of these. you can read compact flash cards on your amiga with the help of cfd and fat95 utilities found on aminet. a600 is a great kit for writing adfs.

lha is a file compression tool for the amiga. think of it like zip or rar for the amiga. you can get lha here. just get the file file lha_68k from that archive and rename it to lha.

Creating a lha archive at windows can be tricky. try this :
you have the adf2disk.lha downloaded from aminet right ? make a copy of it. open that archive with your favorite windows archive tool. put your adf inside. remove the adf2diskrelated files. now you have a lha file containing your adf.

no, you need to keep lha as executable, so you can run it.
As I said, copy lha to workbench:c (here workbench signifies whatever you called your system partition). then you copy the lha archive containing your adf to somewhere on your hd, and run the command "lha e your_file.lha"
