it tells me along the Status line at the bottom of the software window how many messages are in the opened folder. Have you tried that?
If I right click any individual post in a folder, I can choose "Save As", and save it to any location I want. If you have to do that individually for each message then obviously you would not want to burn, (copy), to a CD one at a time, so I suggest you create a temporary folder to store your saved emails in, then burn the whole lot to CD all at once.
I can't say this is what I have done because I haven't. I see emails as notes, and I rarely save any over a few months.
I have a large number of SENT messages. Is there a way to determine exactly how many? And how much space they are taking up?
Is there away I can save selected messages on a diskette or a CD?
