Damaged assets

Couldn’t find this in the forums…

When opening a project I get a series of alerts saying that various items are damaged and should be deleted. The movie works perfectly, including a flv that is supposedly damaged. The rest of the damaged items have such cryptic names as <image>.

Except for the flv, I suspect that these are related to art imported from AI and I have found many scattered throughout the AICB folders that have identical names (such as <image>). The alert provides insufficient info, so how do I know I am deleting the correct items?
