|The difference in the two programs is that Roxio Direct CD can use a CDR for the media. Can't really erase so when changes are made to a file it simply marks the original as "do not read" This just wastes disk space but allows you to use the cheaper CDR media. |
Nero InCD can only work with rewritable media. Other than that both are similar. As mentioned, they are called packet writers. There are some legitimate uses for them.
As you may have discovered, older versions of the packet writers may not be compatible with newer versions of Windows.
If you didn't close session or the disk when using either of those programs then the files can't be read on another computer. Additionally, there are two methods of finalizing the disks. One only allows the disk to be read in other Windows computers. The other allows any computer to read the disk.
If you go to Control panel> add/remove program and check the installed program for either you will get an option to remove or modify the program. Choose modify and then you go back through all the options. There are sub-selections with some of the options and you expand them and either check or un-check as necessary.
