A CD is not a hard disk and not a diskette, and you can't replace files on it, like you do on hard drive or a diskette. It's as simple as that.
The way to use a CD is to burn a bunch of files to it, and that's it. Anyway, that's it for a CD-R. With a CD-RW you can format it again and write another bunch of files to totally replace the first. In fact, it's a little bit more complicated if you consider multi-session disks, but I can't tell you about that because I've never used the feature. Better keep it simple.
For the burning you can use either the (somewhat unclear) native Windows XP way you used now or a burning program like the free one from www.cdburnerxp.se or the program (like Nero) that came with your burner.
Find a better way to store, organise and backup your files. Consider a CD as a backup medium only, and don't edit files on it. A backup is a snapshot you can't edit.
I used "drag & drop" to move some of my documents to a cd rw disk on my D drive. It all transferred well, however, when I open the files and edit them it does not allow me to "save as" on that same cd on the D drive and says, "You do not have permission to save in this directory. See the administrator to obtain permission. Would you like to save in the My Documents folder instead?"
So it wants me to save what I have on the D Drive CD RW disk back to my C drive on my cpu.
This is my computer, I am the administrator and have full permissions so I do not understand why I can't edit and save my own cd's.
Can someone give me the steps to resolve this? When I rt click on the cd drive or disk there is no tab that says "security" as suggested in some of the help menus.
I have Windows XP Home Version and it normally works well. I do not understand why I can't edit my own cd's and save back to them.
