- The program 'XFH' (written by yours truly) included in the Xpk release
- does something along the lines of Stacker, though it's done on the
- file system level whereas Stacker (I think) operates on the device
- level. Unfortunately the current version (like the PPPatches) does not
- automatically compress files, but this will be implemented eventually
- (I'm working on it). The advantages of the XFH are that it is very
- system friendly (being a file system handler), that it is flexible
- (can be selectively applied to directories and co-exists with any
- normal amiga file system), and that it uses the Xpk standard,
- providing a selection of high-performance compression algorithms (you
- could even write your own).
-
- The Xpk package is freely distributable; it was released on the german
- magazine "AmigaPlus" a few weeks ago and may also be available from
- some ftp sites.
