HJSplit is both a Free File Splitter and File Joiner in one. This utility makes Splitting and Joining Files Simple! Created by Freebyte, this portable software can be used to Split large files into smaller chunks (.001, .002, .003 etc) so that they may be sent via email or other methods that impose file size limits for transmitting files. HJSplit can even split files larger than 10GB and checksums can be created. Split files can then be rejoined using HJJoin tool (also included) with HJSplit.
