SPLITFILE
SplitFile's goal is to split (chop) a big file in smaller segments to be able to store them in floppy disks or CD (or in any other device).
It's main feature is the ability to support very large files (up to 9,223,372,036,854,775,807 bytes = 8589934591 GB).
SplitFile can also be configured to increase performances if used with fast disks (adjusting the read and write buffer up to 32 times the commonly used value).
SplitFile has a nice user interface and is easy to use.
