We need to copy common game files in first step.

How to move the unmovable Steam game to a new library example with War Thunder game. In the first step, we need to go to “steamapps/common” folder in the Steam library. In this folder, we have a common launching game.

Next, we need to check the ID of the game for example War Thunder has an ID exactly 236390 number. We go to the Steam library store and get an ID from the link in the browser.

In the next step, we need to copy Steam-specific files from “steamapps” folder we move “appmanifest_236390.acf” to the new library Steam location.

The last step is to move cache files from „steamapps/shadercache/236390” to the new Steam library folder.

And voila the game is working in a new Steam library folder.
