Hello everyone!

An thanks to Kovid for this wonderful too that is Calibre!

I have been a Calibre user for about ten years (now 7.15/W11), and I manage about 45000 books, without too many issues...However the issues I have had recently are a bit strange:

1) on my main library, when I make a research via author or series, some books are missing for no reason...and yet they are in the library folder in their proper place, and so far (say one year ago) there was no issue...
So I tried to restore the database...same issue!

2) I made an experiment and duplicated the Calibre folder under another name via the export/import process using an intermediary folder...I obtain an exact duplicate of the original database, with the same books still not considered in the metadata.db

3) Having a full library to play with, I try to restore the database: this time the original database (75M) is "destroyed" (albeit saved) and replaced by a 5 book database or so (404K)!!! I try again, same thing!

4) I try a last test, and remove the metadata.db, hoping the restauration will force Calibre to recreate it via the books data in the Calibre folder (like it is supposed to do), thus allowing me to get all the books: no dice I still get the same small database!!!

What could happen?

Thanks for your lights!
