Can anybody answer a question? )

I tried to find an answer to my question on this site at on-line help to product, forum etc, but cant find it.
Tell me, please, somebody, can Visual Patch while finding difference between two sets of files find difference in files which packed in 2-level archive?
particular example - i have two msi-install packages with different versions. this packages contanin iso-file (each one) and each of this iso contain gz-file. this gz-file in its turn contain many files in which i need some software to find diff and make a patch. Can Visual Patch do it?

Sorry for my English ) If I explain something not clearly i will try to explain in another way )

VP will find differences in the FILES you give it.
If you give it zip files (or iso or gz) it will find the differences of those files; not the files those contains have.

No, Visual Patch doesn't automatically unpack archives and difference their contents.

However since the runtime behaviour is scriptable, you could create a system that uses actions to unpack the files, applies a patch made for the unpacked versions, and then re-archives them. It would take some work to set up, though.
