Writting files on a CDR permanently but add some later

Generally, if you are using Windows XP, it will allow you to write on the CDR by simply Copying and pasting the file on CDRW drive and then burn it. You can use the remaining space later with the same CDRW drive. But, in case the file size exceeds 90% of the capacity of the CDROM, then it will show that the disk is full.

Further, using NERO burner, you can do the same, in any version of Windows.

Writting files on a CDR permanently but add some later

If you want to still add more files to your CD-R after burning, don’t close the disc after burning. This will allow you to add files later. There are two types of optical disc recording technologies: recordable (DVD-R or DVD+R/CD-R or CD+R) and rewritable (DVD-RW or DVD+RW/CD-RW or CD+RW).

Both technologies are designed to write data to an optical disc using a CD or DVD recorder but only rewritable discs are able to erase or delete and rewrite data. “R” format CDs and DVDs can only be written once and read unlimited times. The “R” type will allow you to burn only once, that is, if you close the disc after burning.

In “R” type, you can have multi-session burning as long as there is available space on the disc and the disc is appendable or left open after burning. You can find this option in your burning software something like a checkbox labeled “Close disc.” When you check this box, it will close the disc and no further burning is allowed.

You need to leave this box unchecked. Leaving the option unchecked will allow you to still burn data as long as there is enough space on the disc. In “RW” type, the disc is automatically rewritable. You can burn and delete files from the disc but still the disc has to be left open or appendable.

If you close the disc, you will no longer be able to add or delete files from the disc. The “DVD-R” and “-RW” formats are approved officially by the DVD Forum standards group. The “DVD+R” and “+RW” formats are not approved by the DVD Forum standards group but instead supported by the DVD+RW Alliance.

The DVD Forum standards group was founded by Hitachi, Mitsubishi, Sony, and Time Warner while the DVD+RW Alliance is supported by Dell, JP, Sony, Yamaha, and Philips. With a DVD-R, small marks are placed in the grooves of the disc which verifies how the DVD reader processes information on the disc while with a DVD+R, it doesn’t have these “land prepits” or tiny marks but instead measures the wobble frequency as the laser processes the disc.

If you need to burn CDs and or DVDs, you can use ImgBurn and DAEMON Tools Lite.
