I have performed a full backup with Elements Organizer 12 to an external hard drive and now want to perform an incremental backup. The "Backup Catalog to Hard Drive" dialog asks me for the "Previous Backup file." I cannot find a file that it will accept. There is no *.tly file on my Mac or the external drive, and the dialog does not accept *.buc. It also does not accept any other file located in the catalog folder. What file does it want for "Previous Backup File" and where is it located?
I have verified that I am looking in the correct catalog folder by clicking Help > System Info and have also searched the entire Mac and external drive for *.tly. I have also made all hidden files visible.
