Is it possible to create a backup of photos on a CD or DVD with Toast 7 such that individual files or folders can be removed from it later?

I've tried several alternatives with CDs, always with the advanced Recorder Settings on Write Session, but any attempt to remove a file from a burned CD always produces a message that I don't have the necessary "privileges."

Is there a way around this problem?

Read up on the ISO format.  You can write multiple times to the disc and each time the file tables will be updated with new data.  It can be done, but its a little tricky.

You can use the ISO format but you must remember to import the previous session. You can only do this on a CD  and NOT a DVD as there is no multi-session DVD standard.

Files can't be removed (deleted) from a CD or DVD once the files have ben burned onto the CD or DVD. Multiple sessions can be  burned onto an ISO 9660 CD (not DVD) and the multiple sessions will appear as a single volume if the CDXA setting is used (see Toast Help for how to do this). One can also add a session to an ISo 9660 CD and have all the earlier ones not appear after the latest session has been added. Again, this is all described in Toast Help; however, individual files cannot be removed (deleted) from the CD without erasing the whole CD. If by "removed" you mean "copied" then, yes, one can copy a file from an ISO 9660 formatted CD (or any other type of data CD or DVD) just as easily as if it was hard disc.
