Does anyone have any bad >experiences of using the system? I've been using LZEXE for two weeks now, and I've not run into any problems at all. As mentioned, the only problems occur with overlayed programs, programs that save options, like configurations, within the program itself, and programs that verify themselves before running. Everyone should be use the latest version .91 since the earlier version would create compressed files that would take more memory than the original program, because of the way Microsoft compilers can pack .EXE files. Get a copy of UNLZEXE. It should have a copy of the source code for UNLZEXE so that the curious can gain a little insight into what LZEXE does. Another freeware program, LZESHELL, will make working with LZEXE a lot easier. It is a shell that automates the process of converting .COM files, unpacking Microsoft EXEPACK files, running UNLZEXE, and translates the French prompts into English all at one time. For the security conscious, the various virus-checking programs will not detect a virus in a LZEXE-compressed program, obviously since the virus would have been compressed into something else. There are also programs available that will scan for the presence of a LZEXE-compressed file. Eugene Wang@bucsf.be.edu
