@Finfan - I get the impression you have missed some calibre fundamentals: The primary point of control of a calibre library is its database, it gets built in memory when calibre starts from the metadata.db file in the library folder. The file system is only used as secondary (backing) storage. And the primary units of data in a calibre library are books, not files - i.e one adds, converts, edits, sends… and removes books.

An hour for 'thousands of books' seems rather quick to me, how many thousands?

Others responders may care to comment

Having originals and the library on the same drive wouldn't be a problem, there are probably millions of calibre users who have everything on single drive laptops.

Library folder 48.2 gb - my folder 80 mb. That can't be right in any case.
What software did you use to remove 'files' from the calibre library? From the above I am guessing Windows File Explorer or a similar 3rd party file management tool. That's not the way to remove 'books' from a calibre library, that's the way to corrupt a calibre library.

But, assuming you used File Explorer or similar, you would have had to navigate calibre's library\author\title tree, i.e. something like this:

Does that ring true?

If it doesn't, and the files you deleted were in a flat folder structure then, as you've already suggested, you were deleting the original files.

I guess you don't have a backup of your original "P:\Books" folder Ψ³
