I have mistakenly clicked the download Dota 2 workshop tools button inside the game. Now it is downloading 5GB of content. I don't want to download this. So I canceled the download from Steam. But after a Steam restart, the download is starting from the beginning and each time I have to stop it manually. Is there a way to stop this completely? Thanks in advance.
EDIT:
I have tried clearing the download folder and clearing the app cache folder. Both do not work.
