There is no history file, but you can find out what routes you have installed.
Open up Content Manager.
- Click on the small arrow to the left of Installed to expand the filter.
- Click on the + located on the far right.
- Click on the small down arrow next to the item that's listed. Usually, it's Asset KUID, but it could be something else; it's kind of random.
- Click on Category.
- Where it says Achievement, scroll the list until you find Routes.
If you want to save this filter for later, click Save and put in a name. You can always reload this later if you add or delete routes and you want to find out what's installed.
