Step 1: Access the Options Menu
Begin by opening the gallery from which you want to copy the filenames.
Click on the three-dot icon in the vertical gallery menu.
From the Options drop-down menu, choose Get File Names. A Lightroom Filenames box will pop up.
Step 2: Copy to Clipboard
From the Lightroom File Names box, click the Copy to Clipboard button to copy all filenames at once.
A green pop-up message will confirm the list has been copied.
You can now paste the filenames wherever you need, such as in applications like Lightroom or other editing tools.
This quick process allows you to conveniently retrieve and use filenames from your gallery in external applications.
