Dariolius allows you to split files using one of several parameters:

Size of each part	Splits the file such that each part is of the specified size. The last part may be smaller. Useful for making the most use out of removable media.
Number of parts	Splits the file into the specified number of parts, each of equal size. The last part may be slightly smaller.
Transfer each part in	Splits the file such that each part can be transferred at the specified speed within the specified time. Files are split into parts of equal size, except for the last part, which may be smaller.

You can split many files at once. Just set them all up, and split. Dariolius is designed to run unattended, so you can go away and come back later to check the results.

Choose between using a batch or program file to merge your split parts.

• Batch files take less space for smaller jobs. Useful for advanced users.
• Program files are more powerful and interactive. They also take less space for larger jobs.

There is also a built in merger with advanced functions including the ability to merge third party split files.

Other programs may have similar features. However, many make mistakes in their batch files by incorrectly using wildcards, which simply won't work correctly once the files have been moved around a bit. Others do not take into account DOS line length limitations, which will cause the merging to fail for large jobs. Dariolius produces correct files tested for jobs of up to 999 parts and correctly reconnects the files in the correct order.

Dariolius has built in email support, so you can easily send large files to a friend from within the program.

Dariolius correctly detects file sizes up to and beyond 4GB, but the free version will only split files up to 2GB. The registered version of Dariolius can split files up to 4GB.

If anybody is interested in funding it, we are able to develop Dariolius to split files above 4GB.

Ideas behind the design

• Dariolius was designed to be lightweight. It doesn't do checksums, because these should be taken care of by either the transmission protocol, or the file copying command.
• Dariolius doesn't detect floppy sizes. The user may not be transporting files on a floppy. They may simply be splitting files into smaller sizes because either 1:their ISP has a maximum file size limit, or 2:they are distributing files on the web, and the person that downloads the file may be the one who will put it on a floppy. It is also recommended that you split files onto your hard disk, not your floppy, as it is faster as well as being less error prone.
• Dariolius doesn't compress files. There are plenty of great zip programs for doing that. This is designed for completely different situations where you want split parts to be accessible.
