Common graphics file extensions:
.AVIWindows Movie. No Apple II program can display this.
.BMPWindows and OS/2 Bitmap format.
.GIFGraphics Interchange Format: Compressed picture.
(IIGIF for //e, many programs for all other computers)
.JPGNewer graphics format. (GS viewers only)
.JPEGNewer graphics format. (GS viewers only)
.MOVQuicktime Movie. No Apple II program can display this.
.MPGMovie format. No Apple II program can display this.
.MPEGMovie format. No Apple II program can display this.
.TIFFGraphics format (GS SHR Convert and others)

Common sound file extensions:
.AUSun (unix) audio format. rSounder 3 can read, AudioZap 2.0 can
read/write.
.MODAmiga Music file. Some GS programs can read & play these.
.WAVWindows file. rSounder 3 can read 8-bit WAVs, AudioZap 2.0 for GS
can read/write, other programs can guess at reading

All 'text only files' files can usually be opened directly in any word
processor, assuming they were downloaded in ascii mode. (Downloading a
text file in binary mode from a non-Apple (Apple II or Macintosh)
machine will probably be formatted incorrectly.)

All of these types, except the ones marked [TEXT] are BINARY files.
Binary files cannot be sent over e-mail, posted to the newsgroups or
FTP'd in text mode. You must FTP them in binary mode (see the section
on FTP). You can download either with kermit, X-,Y- or Z-Modem.

See the next few sections for how to use transfer text, pictures,
general graphics, and sound/music files.

Generally, anything labeled as 'Archive' above can and do contain
multiple files, and even subdirectories. Most archivers (except for
tar) also compress the files so that they take less disk space and
time needed to download them.

Sometimes you will find multiple filename extensions. Simply take the
filename extensions apart one at a time starting with the rightmost
and you should be able to reconstruct the original file. (i.e.
somefile.bsq.tar.Z would mean: uncompress, untar, unbinscii, then
unShrink to get the original file!)

6.4 How do I USE stuff I have transferred to/from an IBM/Mac?

A:If you get a 'File Type Mismatch' error on when trying to read a
file you transferred via a mac, then you will need to remove the
resource fork from the file. See the section on file transfer from
Macintosh to Apple II for where to get that program.

In general, only certain types of files can be usefully transferred
back-and-forth between computers. One thing that you CANNOT do is run
programs designed for another type of computer. But often you can
transfer data files between similar programs (Spreadsheets) on
different platforms. Here are some pointers:
