I have quite often to compare two zip files under Windows. Usually I unzip each of them into a temporary folder, then compare the folders with kdiff3, then delete the temporary folders.
I'm looking for a way to do this with a single step, i.e. directly tell KDiff3 to compare the two zip files, which then automatically unzipps each file and compares the content.
I guess if this may be possible with the preprocessor command, but the examples seem to refer to text files only.
