I've created a LR catalog of my pictures folder, which has hundreds of subfolders, but after the import, all of the files are shown in the main folder, there are no longer subfolders. I need the subfolders as that is how I organize my photos. What am I doing wrong?
A screen capture of the left side of your Library module might help explain your situation. From your description, I think your solution is to enable the Folder View. If you select an image, any image, and right-click the image and select option 'Go to Folder in Library', you'll have the list of all the folders where LR has imported images. What you won't get is a hierarchy like Folder01 > Folder01a > folder01aa.
Although I'm not recommending reoganizing your folders, you might stop and consider whether spending time on folders is the best way to work in LR going forward. You'll see over and over in video training and from experienced UHH LR users to simply dump your image files into date-stamped folders and ignore folder names / structures. Instead of folders on disk, use your keywords and collections inside LR to organize your images. Collections let you have the same image in multiple virtual 'folders' that can be dynamically created and modified with no impact to the single image file inside of say 20191016-Solder-Field.
