I want to add files on a dvd rw where already some files are written. When I try to do that , all the existing files are overwritten and of course deleted I thought I could add always files on a dvd rw till it was completely full What am I doing wrong ??

WHEN I TRY TO COPY FILES TO A NEW AN EMPTY DVD RW- OR DVD RW+ THE TASK IS REFUSED THE WIZZARD ANSWERS : Disk is full or not writable, please insert an empty or writable cd ???

can someone give me the best way to format a dvd ?
