Step 1
Before deleting any mods make sure that you are not using the mods, which you are going to delete because it can break the game to the point of crashing on start.
And don’t foget to do this all with the game closed.
Step 2
First you need to unsubscribe from the mod you want to delete or Steam will redownload it.
Then you need to know what are you deleting. If you are deleting a mod that adds items or more its located in the “Mods” folder but if you want to delete a custom sub, you need to go to “Submarines” folder and find the sub you want to delete there.
Step 3
So basically you deleted the mods and the mission is done, but there’s one more thing. You need to go to the “data” folder.
Then to “ContentPackages”.
And then delete the last bit of files so they don’t show up in the settings.
You did it!
