One of the new exciting features of Flash CS5 is the arrival of the new source file format : XFL – which is a non-compress, text(xml)/raw assets-based version of the fla format. What is this good for ? Version control to be the first ! As symbols are now xml files, once we making changes we can always tracking down by doing a diff comparison to find out what all the changes are. Secondly, all assets are now exposed and artist can change it any time to make an update.
The disappointed thing is it’s not just working that way. The more i used new XFL format, the more I got angry about how useless it is.
