/run/user/1000: What to do with it?
(lemmy.ml)
My main question is about /run/user/1000:
- Should I avoid touching it?
- Could I delete it?
- Is there something wrong with it?
Background: I'm fairly new to Linux and just getting used to it.
I use fsearch to quickly find files (because my filenaming convention helps me to get nearly everything in mere seconds). Yesterday I decided to let it index from root and lower instead of just my home folder.
Then I got a lot of duplicate files. For example in subfolders relating to my mp3 player I even discovered my whole NextCloud 'drive' is there again: /run/user/1000/doc/by-app/org.strawberrymusicplayer.strawberry/51b78f5c/N
Searching: Looking for answers I read these, but couldnt make sense of it.

- https://forums.linuxmint.com/viewtopic.php?t=412850 So if its a bug with flatpaks I'm inclined to delete a certain db at ~/.local/share/flatpak/db
Puzzled:
- Is this folder some RAM drive so my disk doesnt show anything strange? Because this folder doesnt even show up at the root level.
- Are these even real? Because the size of it (aprox 370 GB) is even bigger then my disksize (screenshot).
Any tips about course of (in)action appreciated.
Something to realise when starting with Linux is that everything is a ‘file’. Sockets, processes, input, output etc. That’s very different from Windows and part of why scripting on Linux is so powerful. You can interact with anything.
So some directories are filled with things that aren’t necessarily files but look like it. Someone else posted a whole list, just realise that under those directories/paths shouldn’t be messed with unless you know what it’s for.
Generally when you’re getting used to Linux, /home/$user (aka ~) is where you put personal things. The rest is managed by OS and applications, don’t worry about it.
Edit: spelling
When I let fsearch index from root, it counted 1.9 million files, which baffled me a lot. Before knowing the things in this thread. A typical windows install can have 50k ~ 100k files, but .... 2 million I thought it was insane.
But in this context its something like if LibreOffice Calc had an API and upon start it registers a filesystem with a 'folder' for every worksheet and a 'file' named A1, A2, B1 .... for every cell. Not real I know but a novice way of understanding.
Something like that indeed.
Every active network connection, every process, every piece of hardware and others are in your file system.
Then there’s also the possibility for linking to a file and links take up no space, but can show up like files.
You can use a command like ‘stat’ to get more information about a file (or directory).
