I had the same or similar problem. I had one folder that had over 3,000 photos in it, showing only ONE photo in Lightroom.

This is how I solved it. RIGHT Click on the folder not showing the correct number of photos, then choose to synchronize, and check the option to SHOW the IMPORT DIALOG box.

Once that is done click to sync. Lightroom will go through and eliminate the photos it 'thinks' are already in that folder. On the right panel of Lightroom turn off the option that stops Lightroom from importing duplicates.

Once I did this all my photos were now visible once I imported them all again. I think my Lightroom got confused and was showing only 1 photo in the folder, and when I went to sync it thought it had previously imported all the other photos. As soon as I told Lightroom to import any, even duplicates, my folder was OK again and now shows all the photos correctly.

Very strange. In one of your images you imply the catalog file is on the F drive too in the folder Archives Pixelyst 04-2018. How are you mounting this disk on your computer? Catalogs cannot be on networked drive. Are you doing this through iSCSI or somesuch?

After 1 week of work on Lightroom Classic CC I think I will give up and go to Capture One.

I'm an early users of Lightroon, I have the full CC version and now since 1 week I can't access to my pictures on my library.

I had try every one of the tips listed

I remove all catalog that I have on Lightroom and build an other one

I uninstall and reinstall Lightroom pointing on the new catolog

I wait almost 2 24 hours days to the smart preview to build up

I wait 1 day to the XMP to build up

I can see every single pictures on the folder directly on lightroom (all pictures)

I can't see no pictures on all folders event If I synchronize

I'd look on every single sub-folder and they are pointing to the good folder

I'm quite bored to pass a complete week trying everything in this forum whit no success, I think I will give up if I don't have an other solution (maybe the last one) to solve this problem. I can say one thing, this is the most shitty LR version that I saw for the early days of LR.

Please help if you have a good idea, I'm desesperate (working with over 200K pictures)

That is very strange. Can you restart Lightroom while holding the alt/option key. In the dialog you get, select "test integrity of this catalog" before hitting open.

I have the same problem, after one week of trying by myself (I use LR since the first version) I can't found out what I'm doing wrong, If the problem persist I will have to look for a new solution in LR replacement since it is painful now, I need to have access to my pictures and just can't...

all pictures Catalog is 188057 pictures

Each single individual folder and sub-folder show the good number of pictures for example 2008 (32399) and in each folder the good number of pictures)

When I want to access to a folder or a sub-folder the message no photos in this folder appear, but I can see them in the catalog.

If I select from all pictures Catalog and try files location, it goes to the good sub-folder but message no photos in the folder appear

What I do up to now:

1) I remove all catalog in my computer and NAS

2) I uninstall LR Classic CC and reinstall with a brand new catalog

3) I re-import all the pictures form my folder (all my pictures are on the same folder on the same disk on NAS and Catalog is on my PC

4) It take 2 days to build all the smart previews

The bad new the problem persist.

Please help me!

Lightroom Expanding and Collapsing all Subitems

In Adobe Photoshop Lightroom there are many places where you might want to expand or collapse multiple items all at once; the Folders list, Collections list, or keywords list for example.

If you hold the alt-key (option on Mac OS) and click the triangle next to the entry to expand or collapse it, it will expand or collapse that entry and any sub entries that can also be expand or collapsed.

Taking it a step further alt-clicking (option-clicking) on the panels themselves will switch them into solo mode, where only the active panel will be expanded, and everything else will just be a title. You can tell if the panels are in solo mode because their open/close arrows go from being solid to being dotted.

One final tip, control-clicking (command-clicking on a mac) a panel title will expand or collapse all panels on that side of the screen.

Further to this problem, I note that when downloading new images both sides of the screen show the correct file structure, but in library mode the left catalog is missing many sub-folders as noted previously.

There are other ways to select images to work on than selecting a folder in the folder panel, i.e. selecting 'All Photographs' in the Catalog panel or using any filters.

To make more folders visible in the folder tree, right click on a folder and select ' Show Parent Folder'.

What is your OS and what is the folder location that you don't see?
