The way it used to work,, was you had to format the CD,
do not finilize the CD,, that will prevent any more writing to the CD
Then put the pictures on.
to replace a file, you had to move all the files off,, reformat, then put all the files on, or simply rename the file you wish to put on the cd to a different name.
That is the way it used to work for me with rewriteable CD's
Although with my new CD drive, and new CD software, I can open a word document and make a change, and save it back to the CD drive(without reformat, or moving it to the hard drive). not sure if it is the drive, or the software that I am using.
Drive, iomega Super dvd drive
hot burn pro
nero 6 ultra
What drive do you have, and what burning software ?
