My backup file does not open in file viewer. What can I do? Is there any limitation for entry in the desktop edition and is there any time limitation for this edition?.
Not sure what you mean but perhaps you can post some screenshots. There is no limitation for number of entries in desktop edition.
What operating system? What version of Manager? And what edition (desktop, server, or cloud)? I ask because backup files do not have a .backup extension as implied by your title.
