Move a file out of "Miscellaneous Files"?

First time here, so sorry if i'm posting in the wrong place.

A friend was playing around with some files on their Samsung tab3 and changed the name of their "Pictures" folder to ".Pictures.". Now the file has been relocated into the "Miscellaneous Files". Is there any way i can locate this file, rename it and move it back where it belongs?

I have tried searching for the file both from the device and from the computer via USB. Even with "View hidden folders" enabled on the computer, still nothing shows. Google hasn't been to helpful as every link that contains the word "Miscellaneous" is about deleting misc files. I have also attempted to manually browse the tablets file structures from the computer, opening every folder... there are a lot of folders...

TL;DR: Does anyone know the exact file path for "Miscellaneous Files? Is there a way i can move a file out of "Miscellaneous Files"?

Any help is appreciated. Thanks in advance
