Much like file folders on your computer, CoachAccountable has several contexts in which your items can be organized into folders, including:
In all of these contexts, the same rules and functionality apply.

Let's see how to use and manage folders in CoachAccountable using a Courses collection as an example.

The top bar of a folderized collection contains two buttons on the right: the view mode toggle ( ) and the add folder button ( ).

The left portion of the top bar contains the folder path of where you are currently.  Clicking the folder names themselves will jump you to the respective folders.

Below this tab bar is the main area, in which you'll find both folders and the items contained within.

Creating Folders

By clicking the add folder button, you can create a new folder.  The new folder will be a sub-folder within whichever folder you are currently viewing.  You can create hierarchies of nested folders as deep as you like.

You can also create a new folder by right-clicking anywhere in the main area and choosing "Add folder..." from the context menu that appears.

Tip: CoachAccountable will automatically remove any folders that contain no items when you leave an area, so be certain any folders you create are ready to receive at least one item!

Moving Items Into and Out of Folders

Drag and drop an item over a folder to add it to that folder. If you'd like to move an item out of a particular sub-folder (and into the level right above it), drag and let go of that item over the Up button. 

Toggling View Modes

There are two ways you can view a folderized listing: card mode and tree mode.

By default, views are set to card mode.  By toggling the view mode, you can switch between card and tree modes, which looks like this:
Tree mode is particularly handy when you want to see the complete listing of all items and folders at once. It also makes it especially easy to move folders and items (by drag-and-drop) in and around other folders.

Renaming and Deleting Folders

By right-clicking on a folder, you'll bring up the context menu like so:
These options will allow you to rename or delete the folder.

You can only delete folders that themselves have no items within.  Given that many items in folderizations often have a life out of merely existing in those listings (such as Library Files that are shared or Courses that are in progress), it's a good thing to be assured you won't accidentally be deleting important items when merely meaning to clean up your folder organization!
