dicked the check library and it said was fine but asked if I wanted to check files in library to see if they matched info in the database. I told it to do so and it showed:
Missing book formats and also
unknown files in books
Could this have been caused when calibre was switched from my old computer to my new one? Had to get a new computer and a guy hubby knows who is over the computer department said he would do the transferring for me. I asked him to just transfer over Calibre, my pictures, word docs and favorites (internet), the rest was junk so I didn't care if I lost it. Could in the process something have happened to the files?
From looking at the ones missing, they are the ones that I had in the library first, the others have been added after the swtching.
So, now what? They are all freebies, I can replace them without any problems if it would be easier to just delete them from Calibre and my reader. I had planned on giving them new covers anyhow, and learning how to fix problems such as spelling, grammer (if that is easy to do, I'm not a computer person, in stages I would be in toddler

)
