We probably can't make any serious changes to the DLL architecture until release 2.0.=20 Until then you'll have to make a copy if you need reliability. Or, maybe you don't want to allow the user to Cancel? Sorry if I sound like I don't care. It's just that you're asking for a lot. We haven't went down that road yet.

And if I have a 200 MB zip file? It could take too much time to copy = from one location to another, don't you think?

This was a documented limitation in the earlier releases. Apparently that doc file didn't make it into the releases Chris Vleghert made. The DLLs never make a copy of the zipfile for safekeeping. That's up to the user program. In the early days diskspace was hard to come by, so I decided not to make automatic copies.
