Nero 6 and 7 have InCD which allows packet writing to CDRWs. As matter of personal opinion I don't think that CDRWs make a very good medium for that type of work. I used to run into compatability problems with other PCs when I tried it. However this was some time ago and somebody else may dissagree and say they use it like that all the time. One of those USB keys is much better for that with occasional backup of a whole data set to CDRW which potentially doubles your security of access. CDRWs are now very cheap, but I would stick with something reasonably well known if your data is really important. I have occasionally run itto the odd frustrating problem with really cheap ones.

Second, if you are storing, for example texts or photos on a CDRW, is it possible to delete and replace individual files or is it only possible to delete and rewrite the entire contents?
