2966.0. "PowerPacker V2.3a Don't Leave Home Without It!" by DICKNS::MACDONALD (WA1OMM 7.093/145.05/223.58 AX.25) Fri Sep 29 1989 11:59

PowerPacker V2.3a

This may be the most useful utility available for the Amiga. It is
completely menu driven and has a built-in (moronically simple to use)
scripting routine for doing batch jobs. What does PowerPacker do? Well,
it takes any Amiga executable and crunches it to about 50% of its
original size. You typically use it for files larger than say 1800
bytes. Despite the crunched size, the file still remains executable!
For example, I crunched SEDT down to about half its size. Platinum
Works! is now 400K rather than 800K!! The savings is dramatic. It is now
possible to add VLT and SEDT along with QMouse to an ARP Workbench
V1.3.2 disk that has had the executables crunched.

I have feed up huge chunks of space on my hard disk by crunching
everything in site. For you floppy-based users, GET IT! It's free!

BTW, PowerPacker V2.3a has one of the nicest and quickest user interface
designs I've seen in a long time!

    Where do we 'floppy disk based users' obtain a copy of this most
    useful utility ????

There's a POWERPACKER22A.ZOO on WJG::AMIGA:.   This looks like 2.2a whereas
the base note says 2.3a...

2.3a is the latest.
2966.4PowerPacker questions...SMAUG::SPODARYKBinary ThrottleFri Jan 05 1990 19:4610
    Where would V2.3a be located?
    
    Is this primarily useful for 'crunching' executables? Can I 
    'crunch' my IFF pictures, and then have PowerPacker 'expand' 
    them automagically for viewing with something like Superview?
    
    What kind of performance hit does the 'de-crunching' phase
    take when you want to run an application?

    It can crunch executables and text files, but you have to use the
    'more' program included to view those files.
    
    It won't do iff pictures, but I have seen one that does something
    like that.  If I run across it soon, i'll upload it.
    
    It does seem make some programs load faster, but the de-crunch part
    sometimes offsets that speed.
    
    I have noticed that many crunched programs eat memory but does not
    give it back.  Dunno the reason why.

You need ppmore to view the "crunched" text file. Of course, you can
decrunch it and use any standard text file viewer.

IFF files don't seem to compress. For some reason, they tend to expand
when these compression programs are used.

Hmmm .. I doubt that they load faster. The file is actually decrunched
into memory and then run, so naturally it takes a few moments longer.
But, you'd need a pretty accurate stopwatch to notice the difference on
smaller programs.

I haven't noticed that. Have you tried "cleanram" or "flush" to free up
memory? Have you tried running the same programmed decrunched to compare
memory loss?

    I grabbed PowerPacker 2.3b off of one of the Fish Disks (#253, maybe)
    and have played with it a bit.  It does seem like a real nice
    utility, and I have crunched some of my larger applications
    down to ~1/2 their original sizes.
    
    However, it doesn't seem to crunch anything compiled with Lattice C.
    It comes back with an 'unknown hunk' type error.  I know the
    program will remove symbol/debug information to save space.
    How is the compression related to the types of hunks it finds
    in the executable?  What compression/compaction algorithms might
    it use?
    
    ~Steve ( no problems with PowerPacker 2.3b and memory usage )
