For all Apple II questions, start with the FAQ:
http://home.swbell.net/rubywand/A2FAQs1START.html
What are the various options available for
getting disk images onto media that an Apple ][
can read?
What disk images are you starting with? .SHK,
.SDK, .DSK, .PO, .DO, .IMG, .HDV, .NIB, .2MG, or
other disk image file?
What hardware are you starting with? Apple II,
II+, IIe, IIc, IIgs? PC? Macintosh?
For 5.25" disks, the simplest and cheapest setup
is a real Apple II to write the disk. You can
get the data there via the game controller port,
a serial port, or over a network. Hardware to
write Apple II disks using a PC exists but is
rare. The Mac hardware is an Apple IIe card.
For 3.5" disks, the rules are different.
Another way is a compact flash drive. You can
remove the CF card and plug it into a PC to
transfer files.
