[Ham-Computers] How Much Memory On A CD?

[Duane Fischer, W8DBF]

Hi All, 	
	
What is the maximum storage on a regular single side CD used as a CD -R?	
	
Is there a built in limitation to the number of directories it may contain?	
	
The reason I am asking is because I am showing insufficient disk space on a new
CD with only 338 Meg used. 	
	
thank you.
