I have been trying to consolidate various files on DVD-R as a Data DVD using Nero 7 Ultra, but after I burn the first session and try to add more files later, it not only will not accept the said DVD but it will not even cache the previously burned files. Am I to understand that you cannot make a multi-session data disk on a DVD-R? The disk being used is a Verbatim 4.7Gb DVD-R

You can make multi-session DVDs in the same way as Windows makes multi-session CDs, but they don't enjoy general compatibility across all hardware available, plus support for this is generally non-existent in versions of Windows earlier than XP.

Windows XP will only show the LAST session on a multi-session disc (DVD or CD), but when you burn a multi-session disc in Nero or other burning software the default is to import references to all files written in previous sessions, so the last session will usually contain the files you just added as well as all the files previously written.

Well I tried it again using another DVD-R and made sure that multisession was checked off bu this time it did cache the previous files and showed them in shadow, and I added more files, but when I went to burn I got a burn failure. So maybe I'll just have to go back to making CD Data disks.
