Thanks a lot. Not sure why I haven't see the rename options before. I found them now. Perhaps the renaming doesn't show for all the folders. Gotta check that again. In download folder it works.
Is there a way to rename a video file or any file using the extension "Native File Manager"? Could the renaming feature be added to the manager? So far I have not found a way to rename files stored or downloaded directly to the quest 3 from the internet.
