You can add or remove a reference from a folder by checking the box next to the reference. You can select multiple references at once.
To add a reference to a folder:
- Check the box next to the reference(s)

- Select Assign to Folder in the top left corner of the tool bar (it will become clickable once you select a reference). Select the folder where you'd like to add your reference(s). You can either select a preexisting folder or create a new one.

- The reference(s) will be automatically moved to the location that you have selected
- You will see the numbers after the folder name change as more items are added to a folder

- You can also see which folders any reference is in from the All References view. In the reference record, the folders are in blue underneath the article title.
