Discovered when looking for a book today that many of my library entries have no formats associated with the file.

In October 2015 I had a similar issue caused from a synch error with dropbox where I previously held my library. When the 10-15 error occurred the library was corrupted, many things unsynced. I was able to restore the library via a backup of the entire library. In the restore I moved my library completely out of dropbox to prevent this happening again. —Meant I gave up ability to access files on other devices, but worth it for safety—

At the time, when I restored, not all files were able to be matched back up with their metadata/library entry. I readded by hand several hundred files...

——> back to now

I ran a library maintenance and found that over 3,000 entries had no file format associated. Not knowing how to fix, I imported the backup I used to fix the library in October.

Now I'm stuck with cleanup trying to merge together library entries and it is going to take a ridiculously long time.

How do I avoid this again?

The library should not be syncing with anything. I cannot ascertain how or what happened. I haven't run anything particularly special with the library since the last debacle. I have only added a handful of books. I don't sync via calibre with any devices. (I use rudimentary kindle app 'send to kindle' to read through Kindle program on my ipad)

Can anyone advise on what could be going on? I just want to protect my library and not have to go through this again.

Could this have happened because of an update? That is the only action I have taken with the program. Please and thank you
