I just loaded Lightroom as a trial and created a Library from the same file folders that I have used for my PSE9 Organizer. There are about 4 times more images in my PSE9 Organizer than are shown in my LR Library. I tried to import the PSE9 Organizer information into LR when I started, but I only got about 1% of the images, so I decided to manually build the LR Library from the same MS Windows file folders. I want to learn LR and use its Library, but I am confused by this small issue. Any suggestions on how to get PSE9 Organizer and LR Library to appear the same?
I just compared my Organizer PSE13 catalog with the converted version I made yesterday in 5.7 version. I think everything is converted except maybe a small quantity of file formats not supported in LR. My Organizer shows 54203 items (xmp sidecar files are not included) and LR shows 68 215 in 'All photographs' in the Catalogs tab on the left. I don't know where the difference comes from, but if I have a look in the pse catalog with a sqlite utility, I find 68 489 items in the media table.
If you have file types that are not supported by Lightroom, or duplicate files, these will not import into LR.
