Windows XP can automatically unzip compressed files. But they need to already have a .zip extension.



Does anyone know how I can associate other file extensions (such as .jar) with the built in uncompression program?

I know how to change file associations... just not for the built in compression program, because I don't even know if there's a particular program it uses so I can't browse for it.

You're right, the built-in zip en/decoder is not a standard program file, it's a .dll (zipfldr.dll) that's enabled or disabled in the registry. Unless you turn it off or replace the file association, that's what's used.



To your question - zipfldr is zip specific. It doesn't include support for other compression algorithms, e.g. jar or rar.

Thank you. That's exactly what I needed to know.



For kicks I tried associating a jar file with that dll file, but of course it wouldn't let me. Which is stupid because if I rename any .jar file to a .zip it opens it without any problem. So it is capable of opening jar files if it thinks they're a zip file.

jar uses zlib compression so in terms of compression or uncompressing it is zip. it is only different in terms of the non compression functionality
