There is another easy way to get a manual backup besides the great app imazing. iFunbox is another easy and free app that will do a complete backup of your iPad. Fortunately it’s easy to use and fast.
Simply, connect your iPad to your Mac or PC, then run iFunbox and use the disclosure triangles on the left to access App File Sharing and unrealBook. The right side will show all of your files. Command-a will select all files and command-click will select or deselect single files. Use the Copy To Mac button to copy all the selected files to the Mac. That’s it! Now you have a manual backup of all of your files. (Note: do not copy the inbox when copying the files back to the iPad or another iPad – just skip that folder).
Things have changed drastically with Catalina/Big Sur. To get your files into unrealBook or unrealBook Mobile, connected the iPhone or iPad to a Mac. Open a Finder window. (The files are now accessed directly in the Finder). Click on the iPhone/iPad icon on the left and click on Pair if it asks. You will need to unlock and “trust” the computer.
Then once the apps are listed under Files, you can click the disclosure button to show the files. Be patient as it can take a while. Drag files into the files area to add them to the iPhone/iPad. Unfortunately you cannot shift select files in Catalina to delete them; you can in Big Sur.Apparently select all and shift click has been fixed in Catalina! Now, it is a viable replacement for iTunes.
