I've not run into that problem with my imports...but if I did,
I'd do a search on the key field (assuming it's not autoentered) or another "never-blank" field with an "=" sign to find all of the empties. Then "Delete Found Records" and make them go away in one step (under the records dropdown).
I also get this... only way is to delete the blanks after import.
Easiest way... write a find script that finds blank records and deletes all
Sorry, I should have asked this earlier. What is the criteria you use to find blank records?
Disregard, I figured it out. Thanks for your help!!!
