Have you found yourself with all those files ending with .001, .002, .003, etc. and don’t know what to do with them?

What are they, you ask? Those files are pieces from a larger file that has been split apart. With our software, 001 File Joiner & Splitter, you can join those files right back together! Or, you can split your own files with the click of a button! We proudly introduce 001 File Joiner & Splitter. 001 File Joiner & Splitter allows you to join and split files of any size and any type. Split files can then be rejoined without the use of this software. The split files created have the extensions of ‘.001′,’.002′,’.003′, etc.
