I'm guessing this might be tough, if not impossible. While it's great to be able to add labels to formats which are critical to my workflow, such as .max, file sequences (.tif, .tga, .png, .rpf, .rla), and others, the ability to really track projects lies in the Metadata. Could some sort of wrapper be placed on a file when it appears in Bridge which would allow this? By the way - Bridge CS4, Vista Business 64 bit.
