FSYS Tool

Extract and repack Genius Sonority .fsys archives directly in your browser. Everything runs locally — no files leave your computer.

Use this tool to:

Extract the individual .dat, .pkx, or other entries from an .fsys archive so you can import them into Blender.
Repack a folder of edited entries back into a new .fsys archive that you can drop into your game's files/ tree.

For the full workflow context, see the importer guide or the "importing the model back into the game" section of the exporter guide.

Extracted folder:

Output file name:
