When I was searching with a file-manager app for some files in the root-folder, it generated hundrets (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.
