This small utility will enable you to split a file with the zip extension in several smaller files

Download it here: http://www.radialsoft.com/pdownload/RSSplit.exe

There is no setup, just download the file and run it by clicking on the file.

Afterward you when you right click on zip files you will have the option to split them in pieces of 2, 20 or 100 megs.

20 is fine for emails to us.

100 is fine for ftp.

2 is fine for small mailboxes

Notice the .bat file created. Run it to rebuild the original file.
