Simple Instructions:
Use folders in the Collection file tree to group files together and make them
easier to find. Folders can be placed inside folders. There is virtually no
limit to how many folders you can have or how deeply they can be nested.
To create a new folder, optionally select an existing folder in the Collection
Tree and click the New Folder button. The new folder appears within the
selected one, or at the top level if none is selected. You are prompted for the
folder's name (default "New Folder").
Folders can also be created by right-clicking over a folder, choosing "New
Folder" and proceeding as above.
