Elements 15: My Catalog back up concern?
I have just completed a full backup of My Catalog of 70,000 images. I was just about to delete my previous backup, which had about 45,000 images, but have noticed that the file sizes of both the .tly and .buc files of the earlier backup are larger than the corresponding files of my latest back up (ie .tly: 30805 KB > 22823 KB and .buc: 339244 KB > 317330 KB). I don't know what the .tly and .buc files contain but would have thought that they should have increased in size. Should I be concerned?
