I just bought a new Windows 10 computer, and am restoring all my Elements 15 catalogs (which range in size from 160 to 650GB) to that computer. The restoration process is taking an unbelievably long time. I just restored the 650GB catalog, and it took a total of TWELVE hours for the catalog to be restored and for all the thumbnails to load. The last time I did this, which was 5 years ago, the restoration time was MUCH faster. Is this likely to have something to do with Elements, or did I get a dud computer? The computer seems to do other tasks in a timely manner. I am restoring my catalog backups from an external hard drive. On my old computer, that 650GB catalog backed up in only 1 1/2 hours, so I don't understand why the restore is taking so long on the new computer.
