An application that can split/join files, calculate their checksum and compare them
HJSplit is developed to help you split files of any type and size. It can split and join files larger than 10 Gb. It can also be used to compare files and as a checksum calculator. HJSplit can also assist you in creating backups of very large (multi-gigabyte) files. Just split a 10 Gb file into smaller 640 Mb parts, and burn them to CD's using standard CD-writing software. Restoring these files can be done using HJSplit as well, using the 'join' function.
