There are times when you may have imported multiple folders into Lightroom Classic yet can not see the parent folder (the folder higher up on the hierarchical structure). For example, in the illustration below, we can see my folders for 2014- 2019 but not the “Image Vault” folder that they are contained within (in the operating system).
To display the parent folder, Control -click (Mac) | right -click (Win) any of the subfolders (2014-2019 ) in the Folder panel and choose “Add Parent Folder”. In the illustration below, we can now see the subfolders in their hierarchy.
If you have the opposite dilemma, where you have too many levels of folders showing, Control -click (Mac) | right -click (Win) the top most (parent) folder and select Promote Subfolder to remove the parent folder and promote the child folder(s). One caveat: if there are photos in the parent folder that you are removing, it’s just like removing any other folder and Lightroom will warn you that “If you continue, all photos in the root folder will be removed from the Lightroom catalog but the folder and files will remain on disk”.
