I have a self-extracting zip file that contains four "self-extractables". Within those four files are the files I need to run a particular program. My question is: Using std.zip and/or std.zlib, is there a way to list/compare the directory structure of a self-extracting zip file and subsequently extract only the file(s) required?

e.g.
mail.exe contains: postoffice.exe, mailbox.exe, mailman.exe
postoffice.exe contains: some.cty, jacksonville.cty, city.exe

I only want to extract city.exe and the contents of mailbox.exe if the date of those files are newer than the ones I already have. If I don't have the files in the archive, then it should extract all (self-extracting archives will be deleted, so it is beter extracting them in the first place). To add a finall twist, I'd like to do this remotely. Is this possible?

Where might I find some examples of this?

TIA,
Andrew

I didn't put self-extracting zip file support in std.zip. But you can examine the freely available source to zip to see how it works. See www.infoz-zip.org
