You can simply use a regular git client to manage your .fmw files. Just be aware that functionality that in some way alters the contents may risk creating problems, e.g. merging different versions. But as long as you treat the .fmw files as if they were binary, you should be fine.

Safe is currently working on how to integrate some git functionality into FME Desktop, but nothing's released yet.

fuhter to that, FMW files are plain text, you can open them in notepad. If they're password protected then they are encoded/encrypted

Thank your response you two. It's kind helpful.

That is correct. But if you let git treat them like a text file and e.g. try to resolve merge conflicts, you're likely going to have a bad time. That's why I recommend treating them like binary files in this context.
