recently, when I updated to #Zotero 7, I missed the pdf file rename patterns of #zotfile.
Now, I found a pattern that works well for me (no dots in "et al", no lengthy "and" between 2 authors, no hyphens, no subtitles).
Sharing it here:
{{ if {{ authors match="[^,]+,[^,]+,[^,]+" }} }}
{{ authors max="1" suffix=" et al" }}
{{ else }}
{{ authors join=", " }}
{{ endif }}
{{ year prefix=" " suffix=" " }}
{{ title truncate="100" replaceFrom="(\.|:|\?)(.*?)$"}}
