You may wish to read about the UDF format or packet writing, which is what
DLA uses, at Alex Nichol's site
http://aumha.org/win5/a/xpcd.htm
The advantage of an application like DLA is that it "preformats" or prepares
a CD-R/W so it can perform like a giant floppy. You drag and drop files
directly to the CD Writer icon and they will be immediately written to the
disk. You can also delete or overwrite individual files in addition to being
able to erase them. And most importantly you can save directly to the disc
from any program that can write to a floppy drive, like Notepad, MS Word,
NTBackup etc. You can even download files off the internet directly to a DLA
formatted CD-R/W. This all sounds grand however packet formatted disks have
problems. One is that unless they are finalized they usually can not be read
on a computer that doesn't have packet reading software installed. You can
not use packet writing software to create music CDs. A major problem is
that these disc are notorious for becoming unreadable. The main cause can be
traced to how they write data. Most packet writing software programs create
a VCache (virtual cache) which contains data that is not burned to the disc
until it is ejected. Incorrectly ejecting packet formatted discs can result
in the VCache data not being written and the disc is unreadable. The correct
ejection is to use the software's eject method rather than using the drive's
eject button. A system lock up, improper shutdown or power failure can also
render the disc unreadable if the VCache data isn't written to the disc
prior to shutdown. Third party software like ISOBuster or CD-Diagnostics
should be kept on hand if you use packet writing as these apps can extract
raw data from otherwise unreadable discs.
