I have a similar program called PowerPacker (written by someone in Europe). This is a truly amazing program... on the average, of all the executables I crunched, I saved between 40 and 50% of the space. I don't have a hard disk, and after crunching them the total loading time (including loading & uncrunching) is actually less than with the uncrunched file. (This program probably wouldn't be nearly as useful to HD owners since you would lose a lot on loading time & presumeably space isn't as big a factor with a HD). It also has a built in hunk utility (allows you to force hunks into chip ram for those old programs that won't run in fast ram, among other things). It also has a script facility for crunching a lot of files overnight or something (it can take a LONG time to crunch, depending on the efficiency you use-- has five different levels). Uncrunching, however, is very fast. Fully intuition based, and the archive also includes two short stand-alone programs for crunching & decrunching data files. If anyone's interested, I'll UUencode it... James A.
