Total Commander have very useful feature - I can use a Ctrl+PgDn to enter on any file as archive. For example, file named file.abc, but this is zip archive for real. I select that file and press Ctrl+PgDn and I can see content that file and work with it like any regular archive file. If that file not archive - TC simply don't enter. This funtion is not limited to zip, I can do that with any supported archive format.
