- Faroul, you are talking about CRUNCHING not decrunching ! For decrunching,
- PP uses a fixed amount of memory, depending only on the size of the crunched
- program.
-
- To ask properly to Don, the answer is yes, PowerPacker decrunches the whole
- program in memory (as for crunching). About this, Imploder is better because
- it allocates much less memory when decrunching. Try Imploder4.0, available
- on many ftp sites.
-
- If you are talking about crunching data, it may be different, and Imploder
- crunches only programs. If you want more informations on PowerPacker, you
- can get powerpacker.library package on ftp too, with include files and how
- to use the library.
-
- ">"> b) decrunch the file sequentially, not killing my precious 1M. :)
- ">"It will only use the mem that is not allocated by any other program.
-
- That's not true, Faroul, when you choose little/normal/large, PP will
- allocate a fixed amount of memory for the speedup buffer (up to 256 K for
- the large option).
- Just look at the powerpacker.library for precisions.
