I've got a legacy project with some bitmaps that were accidentally created when importing from illustrator with ten thousand other vector shapes. One of them is named <Image>_0. When I CTRL+F and search for <Image>_0, I get "No items found". I know it's referenced, because a) Select Unused Items finds nothing, and b) if I copy the main symbol from the project to the stage of a new FLA, all the sub symbols including <Image>_0 get copied with it. But CTRL+F still turns up nothing.
What is the algorithm that CTRL+F uses to find bitmaps? Is there some trick I can use to locate mine?
Your bitmap is used in Symbol <Clip Group>_4 under a Mask. The Magnetic Compass present on Stage seems to use it eventually (deeply nested and masked within it).
Looks like a bug with Find and Replace panel for this scenario -> Item nested within a symbol present within a group.
Please log this and we'll take care of it!
