Collapse PR File Tree

This bookmarklet automatically collapses all expanded folders in the Azure DevOps pull request file tree view. It's useful when you want to quickly collapse all folders to get a cleaner view of the file structure.

The script runs every 20 milliseconds, finding and clicking any expanded folder buttons until all folders at level 2 are collapsed.

It's not very reliable, so you sometimes need to click it a few times to collapse everything.
