I still don't know what this 'text menu' is.

In the main book screen the only thing I can show in the left edge is the Tag Browser. I normally have it hidden and use a keyboard shortcut to Show and Hide it. The book details (where the cover, comments are shown) can be shown at the right or bottom edge, I normally have it at the bottom.

All other file accesses on the system seem to be normal, e.g. opening Word documents, moving the files with Finder and the like. I guess I just must split the library until a move to a larger capacity SSD is possible and practical (the last time I looked multiple tb drives were very expensive).
How long does it take to copy the PDF from where it is into a scratch folder on the 'library' drive - ditto the EPUB.

The PDF and CBZ files I used copied from C:\_scratch (the NVMe SSD) to D:\_scratch (the SATA III HDD) in 2.1 secs and 4.1 secs - which are fractionally faster than the calibre add times. But in addition to copying the files, the calibre add also creates a book folder, updates its database, extracts and writes the cover.jpgs, and creates the book metadata.opf files.

If the copy times are substantially shorter than the calibre add times (e.g. 2-5 seconds rather 15-25 seconds) that suggests something is interrupting calibre's processing - like a virus scanner, content indexer, encrypter etc. Try killing all extraneous tasks.

Also try adding items to a newly created empty library, if the times are significantly shorter then its something related to the existing library. The Job Spy plugin has a tool to list custom columns to a CSV, if you post it we can have a look for any 'oddities'.


Last resort: install Windows under Boot Camp on your Mac
