Adobe Fireworks saves both the master (multi layered source files) as flattened web-optimized graphics in the .png file format.
This is confusing in my workflow and sometimes the master .png file gets overwritten by a flattened web-optimized file with the same filename.
I have adopted the convention to ad _FW to the master file's source files for a while but it sometimes still fails.
Is it possible to make Adobe Fireworks to save it's master files with a different file extension than .png?
(So that it is similar to how you can use Photoshop to save it's files in a .psd file and web-optimized files are .png)
