Go to Steamsteamappscommondota 2 betagamedotapanoramavideos
Make a new folder, name it anything you want as it will only serve as a backup folder for the files.
Highlight every WebM file, drag it down to the folder we just made.
Dota 2 should be good to go.
So after playing and if you want to make sure that Dota 2 isn’t gonna detect the missing files, you need to head back to Steamsteamappscommondota 2 betagamedotapanoramavideos
Open up the backup folder we made, highlight all WebM file, cut it then paste it to the videos folder where it originally came from.
If you’re gonna play again do the first step except making a new folder since we already have done that.
