#505 How to export DefineBinaryData
Some swfs have theirs own BinaryData, how to export it?
You should see binaryData section in the tree on the left. Then you can navigate to DefineBinaryData tag you need to export. Then you click "Export selected" from the ribbon menu on the Export panel, or you can use right click menu on the tag and click "Export selected". Is this enough to explain? Or you have problems with the export?
