Flash doesn't automatically re-encode audio on import unless it's encoded with an unsupported sample rate, but that won't convert it to a different file format. That isn't what causes the file size to increase, that's caused by the history/library duplicating the audio data every time it's saved, which can be fixed with the Save & Compress function. Or just saving it to a new .fla file.

It's still a pretty stupid way to share audio, a regular zip file would be a lot better.


Either way, you reported this, so what exactly do you want us to do about this? Did you actually make any of these sounds? Did you get permission from the original creators to use/share them in the first place? If not, then they're not really your sounds and no one needs your permission to share them.
