Although a cd looks like a drive with folders it is not really a file system. Its written in one of several encoding methods. While one or more encoding methods may support some type of security, a google search only turned up what I was going to suggest anyway, which is to use compression like Winzip to zip the contents up into one or more files then use the compression program's security features to password protect it so it can't be unzipped without the password. Apparently the windows cd-r cd-rw standards do not implement a password protection for the cd.

Thank you for any info on this. George Newlark The NOSPIN Group is now offering Free PC Tech support at our newest website: http://freepctech.com
