[GreenKeys] ISP will not accept file of 33.4 MB

If you're running a Linux (or other UNIX) system, it's easy:

split --bytes=5M myfilename  base

This splits the input file into 5 Meg (you pick the size) chunks
with names prefixed by the string value of "base"; 
thus "baseaa" "baseab" etc.

To reassemble

cat base?? > myfilename

To verify that the inital and final files are identical, run sha1sum
on them at either end.

This is really handy when you're trying to upload an 800 Meg file
overnight on a slow rural net connection.  The line is almost certainly
going to drop at some point, making it impossible to upload it all in
one go.
