the current delphi zip sfx is not compressed, it's just "stripped" and compiled using a special (KOL) "runtime library" (system.dcu etc). its size is about 40 KB. using upx, the size could be reduced to about 22 KB (but upx'd apps still have some problems with recent virus scanners). i don't completely understand how spanning works, so i cannot implement it myself. but if someone has some suggestions how to do it (and it also doesn't increase the sfx size too much), i could try to add it to the sfx. -- rgds, markus stephany mailto:merkes@xxxxxxxxx http://www.mirkes.de pgp fingerprint: C8E9 5DFF 7BE5 99E9 850C 52CC 604A 0452 FA34 F7DD
