Is Your WTF Folder Swimming in Clutter?
While building my custom UI I found out that my WTF folder was swimming in a lot of garbage from past addons. Some of those past addons I used for a long time, while others were one day test. I knew from my previous testing that I could delete the useless stuff without incident.
I found years of useless stuff in the WTF folder. Maybe some of it was causing errors from time to time. Maybe not. I removed all of the addon info files for things I don’t use any more. It was easy due to the files being named after the addons. I will say to be careful if you venture into doing this.
There is a safety net with the WTF folder itself. If you delete the folder, it’s rebuilt when you log back into the game. This may come from server-side, so that useless information maybe back too, but I’m not 100% sure.
