I use the Collectorz.com book database software to manage my book collection. I hadn't updated the database for several months, but I had purchased some books recently and wanted to add those books to the database. When I opened the Book Collector program (version 16.4.3), it automatically opened the last book database I had open, which was one that I use to track books my wife and I have purchased as gifts for a friend who also enjoys reading, so I don't buy the same ones again in the future. But when I tried to find the database in which I store information for my own books, I couldn't find it. When I clicked on File and selected Open Database in the program and navigated to a folder where I thought that database was stored, the program didn't show the database at that location. When I navigated to that directory with the Windows File Explorer, I didn't see any files with a .bkc extension, which is the filename extension used by the Book Collector database program. Collectorz.com also provides comic, game, movie, and music database programs.
