how to delete files on a cdrw

[jgmproblems]

Help! I am using a computer at my local library trying to copy files to a CDWR drive (using a CDWR disk). When I drag and drop the files, they are stored as readonly files and then can not be deleted from the disk. I do not want to delete all the files on the disk ... just some of them. I want to use the cd disk as temporary backup. Please tell me what I need to change to be able to use read/write features. Do I need to format the disk someway to enable this feature? Or do I need to ask the library to change the way they have something setup? Any help would be apprecited. Thanks.

I don't think you can use a CDRW in that manner. The disc is just capable of being re-formatted and re-burned multiple times, which requires wiping out the previous contents.

You might try setting up multi-session burning but I don't recall if that prevents you from being able to access data written in previous sessions.

You can do this with either InCD from Nero or...um...something else I used to use in the Roxio Suite. However, I don't think this type of action can be done with just Windows.

Can erase a CD-RW in Windows XP and up.

Erm, sorry to be ambiguous.

I was replying to jgmproblems - which is to say that either of the apps I mentioned basically present a (formatted by the app) CD-RW as a hard disk like device, with the ability to add and remove files at will and even allow it to be the target of a scheduled back-up.

Maybe Windows previously pathetic CD writing has advanced to the point that you can format a CD-RW and use it thusly? I'll give it a shot

Hmm well if you have Windows Vista there is this new feature called Life File System. It lets you use the CD-R(W) like a floppy disk, except nothing is really deleted.

Have you tried erasing it through winxp itself?...Winxp can write, read, print, etc directly from the cd/dvd player, so with erasing files on it.

i think you cannot delete a single file from a cd. u can format it fully.
