Script to purge the Steam Deck's shadercache & compatdata directories

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, zShaderCacheMover will copy & symlink selected games shadercache & compatdata directotries to the SD card or External Drive where the game is stored, freeing up the Internal Storage.

This has had limited testing on one system, USE AT OWN RISK

For me I had 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 dual boot with Windows 11, this also saves space as the Shader Cache is now in the same location on the SD card.

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
