Thanks, but those all seem to be within the same drive. When I click on the Folders + button I lose access to the ones on the main hard drive. |
I strongly recommend you use the method posted above by 99jon -- move the folders using Finder, not LR, and then relink the new location of the folders to the catalog. See option one in this authoritative Lightroom Queen article: https://www.lightroomqueen.com/move-photos-another-hard-drive-leaving-catalog/
As the article mentions, moving large numbers of folders is safer with Finder / File Explorer -- there have been infrequent but persistent reports of LR losing files when it moves folders:

While one particular bug reported in these threads has been identified and fixed, many of us believe that there are other bugs still remaining.
