Whoa! What a mess now.. I tried saving my last project.. as a cwp. Well the wavs associated with this were a wopping 650MB. The cwb file for this same project previuosly saved as cwb was only 93MB. Also, when I tried to open the .cwp file it took even longer to open than the usual 30 seconds or so that it took to open the cwb. Not so tidy and efficient after all. Something here is not right. I'll check further..
Two possible problems here. First, are you using Per Project file storage? If not then it's likely the wave files you were saving were from this AND other projects as well.
Second, if you ARE using Per Project storage, it is possible you have a lot of "unused" audio in that folder. For ex., takes that you later deleted, etc. Deleting them from the project does not remove the audio files from your drive. However, you should be able to get rid of that clutter with the Clean Audio Disk tool.
