Winspilt

Winsplit: Avoid being forced into the world of CD-Rs and Zip disks when you need to exchange large files between computers. WinSplit is a free utility that splits even 2GB files and more into e-mail or floppy-friendly bites, and re-joins the data into a single file at its destination. Three splitting options let you split the file by size, number of pieces, and at every instance of a particular word (when breaking up text files). There is also a feature that checks to ensure that all of the file pieces are an exact copy of the original.
