What are some common executeable compressors that are easy to work with (and can function by the command line so I can use them easily in MSVC++). I currently use UPX to compress my stuff -- it turns 192K exe into a 32K exe (down to 19% original size). It also compresses .dll''s down to roughly half their uncompressed size -- and they can all still be used normally. However, I am just curious as to what others have found, and to see if anyone has anything better. (i use upx v.1.24)
