SNG File Manager
Create and modify .sng files. Build a new package from a folder or loose files, or open an existing .sng to inspect it, add or remove files, and convert it again to .zip. Everything runs in your browser.
Create SNG
Start with an empty package, then drag in the files or a folder that make up your song.
Modify SNG
Open an existing .sngfile to see what's inside and make changes.
