What about the old CP/M archive files on your PC ?
I've found a very handy tool, written in C from Carson Wilson in 1991, running under DOS and UNIX, named "CFX".
Unfortunately there were a few bugs in that program, like LBR member archives could not exceed the size of 64 KB (if the members were bigger, it was just modulo 64K, means 96 KB were reduced to 32 KB).
I eliminated the bugs and I expanded it with additional functionality like saving expanded files with a date stamp and filename conversion if a '/' was used in CP/M-filenames.
Now you can extract LBR files, LZH compressed and also squeezed files (xQx and xZx) are also expanded automatically.
You can download the executable and the source of the current version CFX 1.3 from my site here.
I've build also a Win32 executable version so you can go on working with Windows Vista or 7 without problems.
A new promising software named "the unarchiver" can be found at unarchiver.c3.cx, not only for Windows, but also for MacOS X. A list of downloadable files can be found at code.google.com ...
