LXSplit 0.2.4 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. LXSplit for Mac lies within System Tools, more precisely File Managers. We recommend checking the downloaded files with any free antivirus. This free Mac application was originally designed by LXSplit Team.
From the developer:
lxSplit is a simple tool for splitting files and joining the splitted files on unix-like platforms, such as Linux, FreeBSD, OpenBSD, etc. It is fully compatible with the HJSplit utility which is available for other operating systems. Splitting is done without compression.
lxSplit was originally written by Richard Stellingwerff, and is now being maintained here at its new home.
