Ask HN: How do you manage versions of non-code files?

[forthispurpose]

Does anyone has a recommendation on how to do version management of non-code files?

For example - sharing presentation with designer for polish, who then makes some adjustments but we still want to keep 2 version to compare and merge later.

Then this presentation is sent out to another customer and some slight changes are required for that. In the end you end up with a ton of folders each with 2-3 versions of the same content..

A Git-type system with branches would be perfect, but you can't force everyone to use command line interface

Google Drive has version management, so you can have keep everything in one Slide file, and review changes.

I think dropbox has it too
