I keep a "file:///blah blah (nnnnnn)/data/" URL, labelled "Attachments", in a Links/#links custom long text column. A search for #links:"attachments" finds the 1,334 books that have data folders in a 19,756 book library 'instantly'.
Prior to the recent changes I already had 'Attachment' folder URLs in the #links custom column. They referenced folders that had the book number as their name - e.g. D:\Calibre\Libraries\Books\!Attachments\123. The !Attachments folder was excluded from Check library.
So, converting to the new scheme was relatively easy for me.
