Not easily -- you'd have to traverse the object graph yourself to see if you can find any references. In particular, I want to prevent some content objects, like images, from being removed from the folder if they are used in some other content object, like a news article. Do I have to keep track of object referencing in ZODB myself through events or there are some built-in mechanism in ZODB to take care of this for me? Your best bet is to keep track of this yourself.
