9.3 File to non-Internet Sites

    What if your friend only connects with a non-Unix system, such as
CompuServe or MCIMail?  There are programs available for MS-DOS, Apple
and Amiga computers that will encode and decode files.  Of course, since
you can't send one of these programs to your friend via e-mail (how would
she un-encode it?), you'll have to mail (the old-fashioned way) or give
her a diskette with the program on it first.   Then, she can get the file
by e-mail and go through the above process (only on her own computer) to
get a usable file.  Remember to give her an encoder program as well, if
she wants to send you files in return.
     For MS-DOS machines, you'll want to get uunecode.com and
uudecode.com.  Both can be found through anonymous ftp at
wuarchive.wustl.edu in the /mirrors/msdos/starter directory. The MS-
DOS version is as easy to use as the Unix one: Just type
 
                uudecode filename.ext
 
and hit enter.
     Mac users should get a program called uutool, which can be found
in the info-mac/util directory on sumex-aim.stanford.edu.
     Think twice before sending somebody a giant file. Although large
sites connected directly to the Internet can probably handle mega-files,
many smaller systems cannot. Some commercial systems, such as CompuServe
and MCIMail, limit the size of mail messages their users can receive. 
Fidonet doesn't even allow encoded messages.  In general, a file size of
30,000 or so bytes is a safe upper limit for non-Internet systems.
