This list shows any special folders that third-party software has added to the desktop. Often (but not always) these are used for cloud storage (e.g. OneDrive, Dropbox). Folders that Opus identifies as cloud storage will:

• appear in the separate Cloud Storage branch of the folder tree if it's enabled
• trigger the Cloud Storage folder format if enabled (to, e.g. add the Status column to show sync status).

Opus will try to identify special desktop folders as cloud storage automatically, but if it gets it wrong you can click in the Cloud Storage column to mark a folder as cloud storage manually. Folders that are identified automatically will show a dark cloud, and folders you've marked yourself will show a bright cloud.

The Show column lets you control where the folder is shown; choose from:

• Folder Tree: Appears only in the folder tree (under the Cloud Storage folder if it's enabled, and the folder is marked as cloud storage).
• File Display: Appears only in the file display.
• Both: Appears in both the folder tree and the file display.
• Hide: The folder won't be shown at all.

Some cloud software doesn't add a folder to the desktop - for example, Google Drive often adds its own drive letter to the system instead. If you use cloud software that isn't shown in the Desktop folders list, you can add its location here to have Opus trigger the Cloud Storage folder format automatically for that folder as well.

(This limitation was removed in Opus 13.9.1:) Note that folders you add here won't currently appear in the Cloud Storage branch of the tree - that only works for desktop folders..
