Looking for a document management system for .story / .ppta / .quiz / .pptx / .zip files (e.g. git hub?)

I've had a lot of success with Box.

Version control is one of my biggest pet peeves, with file titles containing a date, and/or "final," "FINAL," "REALLY_FINAL," "UPDATED_FINAL" and so on being used as a poor-man's sort of version control not actually working.

I have one file title, and each time I save from Storyline, PowerPoint. Quizmaker, Word, etc., to the local Box folder, it updates and versions the cloud file automatically in the background. At any time, I can go to the cloud file, view the complete version history, and if necessary, make a previous version the current version. It then updates my local copy of the file to, syncing it to the cloud.
