A quick & dirty port of Dirk Stoecker's XPK (de)crunching file handler (http://aminet.net/package/util/pack/XFH).

Installation:

1. copy L/XFH-Handler to L:
2. copy one or more of Devs/DOSDrivers to DEVS:DOSDrivers

Change the name of the dosdrivers depending on which device you want it to work on (f.e. XHD4 for HD4:).

Check the (included) original documention for more info.
