I have the 64gb deck and a 512gb SD card.

I recently wiped it and started again due to the OTHER folder taking up all the space despite cleaning and removing all non-steam game folders, moving data to sd etc.

Installed cryoutilities. Used it to move/delete data as I added and removed games a couple games.

Installed Heroic launcher. Installed one game. Played, then uninstalled. Installed Emudeck with only Atari 2600 emu and one rom.

Installed 2 NS games by adding setup.exes to steam. Both installed but crashed on startup so I deleted all folders in desktop mode.

Removed all compat data and shares via Decky.

This is my storage issue. It was almost completely empty as I was only playing and removing steam games after complete reset.

I currently have nothing installed and only proton experimental (on SD).

OTHER size was tiny when using multiple steam games and installing/uninstalling as I pleased.

Just not worth installing emulators and ns games. I need to learn the lesson.

I tried analysing the storage for large folders and it’s the tmp-7BCJE2 folder under SteamLinuxRuntime_sniper…?
