Split and join

Distribute large files in small packages using this helpful utility.

Chop is a fast, lightweight tool for splitting up large files and rejoining them. Its interface is a bit sparse on instruction, but anyone that's not an absolute beginner should be able to start using the application effectively within a few minutes.

The default Chop window lets you split files by target medium or by number of files. You can specify the destination as well, or let Chop create a folder automatically. A wizard option simplifies this process and provides context for some of the fields. If you have additional questions, a clear Help file is a button click away. Chop offers several features that make this program stand out from its file-splitting brethren. The best is the freedom not to use Chop. To rejoin split-up files, you must typically use the splitter program itself, but Chop lets you create a small .BAT file that your Chop-less recipient may use instead. This option does preclude other useful features, however, such as the verification of file integrity using a CRC checksum and the capability to apply a password to prevent "unchopping" by unauthorized users. Although the program performed admirably on files large and small, it is not without problems. When switching back and forth between wizard and expert modes, the program occasionally stopped responding. We had to quit and restart it several times to get it to function again.

Chop (30-day free trial; $8 to buy) is a fast and easy-to-use utility for splitting large files, suitable for most users comfortable with navigating a file system.
