well, so far im impressed. first a quick overview from their website...

"UPX4PPC is an application for you to compress & optimize EXE/DLL files. Programs that are compressed using UPX do not need UPX to be present in order to run. The decompressor is placed on the front of the file, so an additional unpacker is not requred when running the compressed programs."

using the FREE upx compression tool, you can select individual dll and exe files and compress them reducing the space they take up on your device. obviously, you would only need to do this in main memory, and you can only apply this compression to files that are not in ROM, but the benefits should be rather apparent.

now i dont have too many files installed to my device (the majority are installed to external storage (sd)), however i do have webis pocketinformant calander installed with a dll in \Windows\ (PITools.dll)the size of 1158 K. i applied this dll to upx4ppc and clicked "start" from the menu and it asked where i wanted to back up the original and i clicked ok and done. it shows the result.

(with default compression)

original size: 1.13 MB

Final: 612.50 KB

(with Maximum compression)

original size: 1.13

Final: 529.00 KB



imho a massive savings!!

the only issue that has been raised is the extra processing that has to take place for the extraction to occur when a dll or exe is called (to which i havnt noticed, probably because i havnt applied this to too many "always running" or otherwise files).

so far looks neat. ill have more time this weekend to test things out
