This project is a GUI utility for processing files. It allows selecting a set of source files and a pipeline of processes to apply onto those files. The applications shows in a nice-looking user interface where you can define profiles for your repetitive tasks. It provides pre-defined processors doing usual file manipulation tasks like: Copy, Head, Tail, Chunk, Search, Replace, Zip, Unzip... But the biggest value of this file processor tool is the ability to add easily custom file processors written in java.

The newest version!
