Bookends & Devonthink4

Firstly, did you read this…

Secondly, clarify what you’re actually doing, like what this means…

will I not be able to continuously run Bookends imports

… is there any way to delete all the new files that have the word ‘copy’ at the end without having to manually delete them?

Delete them from where - DEVONthink? Bookends? The Finder?
