Resources can be organized in folders and with tags.
Create a folder by clicking the "Create Folder" button in Resources. Move resources into folders by clicking and dragging them. Move a resource out of a folder by right clicking and selecting "Move to parent folder".
Tag files by opening them in resources and adding to the tags field, tags can only contain letters, numbers and dashes and are separated with commas. You can then search your resources by their tags or names.
