Hi,

I have a mp3 file that is 2:30 long and is roughly 5.5mb. How come when I import the file to my fla library it sees it as being 29mb large. My swf isn’t large when I compile the project but the fla file jumps from 2mb to 30mb just from adding this sound file.

Any insight would be much appreciated

P.S. This site has been a ton of help with different aspects of my flash project.
