Need easy to use app for copying data file to DVD

[sandyeggan]

Tried Windows 7 built-in "burn file to disc" software but failed. Tried Nero, also failed. DVD has files already on it that I'd like to keep, just want to add one small file (data only) to it.

what kind of disk it is? only some are rewritable

If the disk is already closed, you cannot add anything to it, whatever software you use. You must take special care the first time you create the disk to make it "multi-session".
