Cloud storage of Adobe Animate files

Dear community members,

For users of Adobe Animate, what online cloud are you using?

I'd like to save my (big) .fla files online so I have a backup and I can access them from different computers. To my knowledge, Adobe CC Files isn't available anymore and the "Files" section from Creative Cloud app is not compatible with .fla files. I heard about Frame.io ? What do you guys recommend?  Many thanks
