Eric, some time ago you were saying that you now work with the Microsoft compiler so your new dll's would need translating for builder. If they link ok with Delphi/Builder why would they need translating (except for Borland enthusiast's who want an all Borland solution) - If you know the tricks of the compiler you normally use the outcome should be better! Years ago I would have tried translating them but now I don't have time for what I absolutely have to do, let alone try to learn the differences between the two compilers. Also - When zipping a broad section of a drive (more so if you are only looking with AddArchivesOnly) there can be quite a wait (presumably while it builds its list of files) before it starts compressing its first file - could it generate the occasional message (i.e. "searching" + count) say every 1024 files. - Russell Peters
