The options on this page allow you to prevent Opus from automatically loading certain types of folders (e.g. when a Lister opens, it will normally automatically load a folder).
This can be very useful if you have Opus set to re-open the last location when it runs, or to open a specific Lister layout that displays network drives or another slow drive type. It stops Opus from attempting to automatically read the specified types of folders when a Lister first opens. For example, you could have a layout that reads a network drive - with this option on, opening that layout would not automatically connect to the network drive, but instead you will be prompted to click a link in order to read the folder.
For each folder type, you can select from three options:
At the bottom of the page is a list that lets you apply the same options to specific folders or wildcard patterns. E.g. you could have network drives set to generally not load automatically using the option above, but override it for one specific server by adding the path to the Folders list.
