(.Ğn╬) file in my Avtivities Folder

Hi everyone,

First of all sorry, I could not find Edge 520 in the list and  had to ask the question here. Recently an unknown file appeared in my Activities folder which can not be moved or deleted with the extension (.Ğn╬). I could not get rid of it whatever I did. I reseted the device to factory settings twice but it did not clear this file.

Any advice?

Thanks in advance.
