Do I have to back up and reset to clean storage from "other" file

[AC Question]

I can move all device storage files on my Android into the sd card except the "other" devise storage file. What is in there?

That's files that apps have saved - your login, your address, things like that. It depends on the app. And if you move it, it's like clearing the data for that app - it's no longer there, as far as the app is concerned ("there", being either "other" or "Misc").
