Hi,

I try to create an on_import filetype plugin that:

Read the current import epub metadata
Read the current import epub name
Create a temporary epub
Apply it current import epub metadata
Modify temporary epub author and tile from current import epub name
Return the temporary epub


It seem to work if I drag and drop pub one by one, but if I drag and drop multiple epub some are not well flagged and it also make duplicate ?

Same problem if I import a folder with multiple epub.

In fact, I not find a good explanation of tempory_file or a sample to make it that way (all my try not working).

I have to say that i'm new in python and calibe dev
I'm on macos 10.14.6 and Calibre 4.9.1

Regards
