It keeps the behavior of the file untouched, but with its size reduced thanks to several recompression and optimization techniques.
Drag the files you want to optimize to the files grid in FileOptimizer, right click with the mouse to open the contextual menu, and then click on Optimize. This will process all supported files added, and overwrite them with the optimized version.
Alternatively you can add the files and directories to process on the program's command-line, or dragging them to the executable file. A context menu for Add files, also does it.
By default, FileOptimizer will remove additional metadata, and other unneeded information, but will keep original files in your recycle bin just in case you want to further modify the originals.
