PE Compact - Version 0.94 A utility that compresses Windows 9x/NT4/w2k executables, while leaving them 100% functional. PECompact compresses the code, data, selected resources, import/export table of a win32 executable and optimizes its structure. It then installs a symbiont which decompresses the executable at run-time without any noticeable speed difference. Load time can actually be improved in some cases because less data has to be retrieved from the disk.
