Starting with version 2016.3 , it is under Settings > Appearance and Behavior > Areas .
Or regardless of version , just go to Settings and enter βareasβ in the search box at the top.
Then simply click on the + symbol to add an area, select the folder you want to exclude, and click Exclude recursively and apply.
Then, when searching using CTRL + SHIFT + F, under Options> Region, select Custom and select the region you just created (thanks to the commenters).
