Hi Jall13. In one of your folders where you know there are events or a trip, can you open the folder and see how the photos are arranged? Are there any sub folders. You don’t have to post an image here (keep it private) but maybe see how the photos are arranged within the folders.
By chance do you rename your filenames of photos and videos? I do, so all the photos of say “John’s birthday” I’ll do a batch change of the filenames to “John birthday 20March2025” for instance and Windows sequentially numbers the photos, John birthday 20March2025-1.jpeg, John birthday 20March2025-2.jpeg, etc. If you had renamed the pictures TonFotos can search by filename even if you’ve lost your file structure.
Another question, do you have a backup of your photos somewhere?
