Script to Purge The Steam Decks Shader Cache & Compat Data
Script to Symlink selected games Shader Cache & Compat Data to the SD card or External Drive
With the 64GB verson of the Steam Deck, "Other" can quicky fill your internal SSD even if you only store Games on the SD card, this "Other" is often Shader Cache & CompatData.
To free up some of the space you can delete the Shader Cache and/or the Compat(ability) Data, the zShaderCacheKiller script aims to make that process a little easier.
Rather than deleting the Shader Cache or the Compat Data, the zShaderCacheMover script will copy & symlink selected games Shader Cache & Compat Data to the SD card or External Drive that the game is stored, freeing up the Interal Storage.
This has had limited testing on one system, USE AT OWN RISK
For me I has 16.2GB of "Other" data, running zShaderCacheKiller dropped this down to ~7GB.
My Back 4 Blood install was also using 3.5GB of Shader Cache, this I did not want to remove, instead with zShaderCacheMover, these files are now on my much larger SD card. As I also duel boot with Windows 11, this also saves space as the Shader Cache is now in the same location on the SD card.

The install script will offer to add zShaderCacheKiller.sh & zShaderCacheMover.sh to your Steam Libaray, which can be ran from GameMode.
To uninstall simply delete the install folder:
sudo rm -r /home/deck/.local/share/scawp/SDSCK
Also remove the non-steam game links in Steam
