Xtractor

A simple tool which search, and unzips all ZIP-files, starting in a given initial directory, without changing the directory structure;
which means that every ZIP-file in multiple subdirectories, will be unzipped in the overlaying directory, without creating new (sub-) directories. Simply by executing one single command.

No libraries, or installation required; simply execute Xtractor, and start with mass unzipping every single ZIP-file elsewhere in your directory, without changing its structure.
