GSplit
Powerful and free file splitter that lets you split your large files into a set of smaller files called pieces. It also creates a Self-Uniting program that automatically restores the original file with no requirement. Finally, it includes a lof of customization features for easily and safely splitting your files.

These pieces are easier to:

• copy to floppy or any removable media disks.
  
• distribute over the Internet, networks.
• send by email (forget attached file size restrictions imposed by some ISP, pop3, SMTP and other e-mail servers).
• archive to CD, DVD, USB Flash drive and key, Zip disk, and any other storage device.
• upload to host accounts, file delivery services, online file hosting sites... that have restrictions on file sizes.
• share with friends, colleagues or other users through networks and the Internet.
• exchange using Instant Messaging clients or Instant Messenger programs...

Make pieces Self-Uniting: GSplit creates a small stand-alone executable file that will put all of the pieces back together. This executable provides your users with an intuitive Windows interface whose appearance can be customized according to your needs. GSplit is then not required in order to restore the split file.
