Title: Compressing the Freespace .exe files
Post by: von Pilsner on January 02, 2009, 09:42:31 am

I compressed the Freespace .exe files with UPX and here are the results. I don't know if it matters too much to anyone to reduce the size of the .exe files, but I thought I'd mention it.

I have used UPX .exe packer (http://upx.sourceforge.net/ (http://upx.sourceforge.net/)) before and it doesn't make AV scanners mad or anything... =) (some packed .exe files throw up a false positive on some AV software). Also, source code is available and it is cross-platform compilable.

I usually call it with a batch file (Win32) but a simple Linux script would be easy to write.

Contents of upxall.bat (Win32)

Code: [Select]

@echo off
upx --best --compress-icons=0 --nrv2d --crp-ms=999999 -k *.dll *.exe
echo Press ctrl+c to quit now or any other key to delete old (uncompressed) files...
pause
del -f *.*~

I have been using the compressed Freespace .exe files for a few days now and haven't noticed any problems...

This might be neat to look at sometime, but I'm afraid the gain might not be worth the risk of another layer with a chance of creating problems.  The builds themselves are distributed 7-zipped or RARed and I doubt the archive would get much smaller, but those who keep a lot of different builds in their folder might benefit from the space saved.  I just don't know if there's a lot of people who keep all those unarchived builds around.  I know I usually delete most of the ones I'm not using.

i keep lots of builds around because some of my scripting demos only work on one particular build, and i like to keep those around for testing purposes. but i really dont have a need to compress them. i usually only let my hard drives get 1/4 full before i get a new one and really dont like to be bothered with compression.
