You are right BetterRed, i gave up by this way.
I have automated it by using ebook-meta.exe in a "Direcory Opus" button, and then work on my titles usign regex in Calibre.
It would have been so simple if i could prevent Calibre to modify my titles found with filenames, with those found in books metadata (or i don't use them, but i lose covers and other metadatas).
Thanx for your help anyway
