When I was searching with the ["File Manager" app (com.alphainventor.filemanager)][1] for some files in the root-folder, it generated hundreds (almost a thousand) folders in the proc-folder.
[I don't have root-access btw., but still can see some files there.]

They're named just 1, 2, 3, 4, etc.
Each folder has about ~40 files in it.

I already found out, that those are virtual files, that eat like no space.
However I would still like to clean those up.

Is there any smart way to do this?
I was hoping, they would be removed by restarting the system or deinstalling the app, but so far nothing worked. :/

I am on an LG G7 with Android 8.
Any help would be greatly appreciated.
