Open Source File splitters

If gsecraif is not the file splitter you are looking for, there are many Open Source alternatives.

File splitters can be divided in to two categories; general purpose file splitters split an original file in to a number of components that may or may not be usable independently. Specialized file splitters "understand" the structure of a particular kind of original file and split it to produce component files that are usable independently. Examples of specialized files splitters are media file splitters and log file splitters.
