Do I need Root to create a new file?

[AC Question]

My GS7 runs Android 6.0.1
This is my first phone without Root.

I've tried Astro, Samsung's "My Files" and File Magic. None of these will create a file for me.

Astro and File Magic created files for me on my rooted phones.

Seems pretty obvious, but I had to ask.
Thanks.

What kind of file do you want to create? These machines create their own files when you download stuff or save things. If you talking photos, you can create albums from you gallery...
