Adding files to a dvd

[blue_screen]

I'm sorta new to burning dvd's, is it possible to leave a dvd open and add more data to it at a later date like a cdr? I have thought about using these for backups, I have about 400mb a day, so if this is possible I could use one dvd for 10 days of backup.



Thanks

first off you can't add info to a cdr only to a cd-rw disk. Same goes for a dvd. You need to use a dvd-rw disk.

Here is a link that explains it better than I can.

You can't add files to a cdr,.. thats very true,.. but you can write to it a second time as long as you don't "finalize" the burn. But if you have data on the cd, and it was never finalized, then you can use the rest of the disk space on it to burn more data to. It just allocates the data to new portion of the cd.

My confus-ed-ness at work ! ;)

You can do multisession with a cdr & it works in any pc but only the first session is available to most 'players'.

Same again with a DVD, but this is data, so pressumably it'll get read by something that's not a non pc source, so no problem with that bit.

You can add to any disk if you've got enough room to physically burn it (as long as the original track isn't finalised - note the 'contents list' won't be 'right' until you finalise) & what you can add & 'delete' (you can't really delete with once only media, but you can change directory listings etc)is only different between write once & re-writable formats in that once the first is full, that's it, whilst with the second you can erase & start afresh.
