Cd-r Vs Cd-rw
Cd-r Vs Cd-rw
TODAY I WAS ASKED BY A CO-WORKER ABOUT WHAT KIND OF CD WOULD BE BETTER TO USE WHEN THEY WENT ON TRAVEL. THEY ARE WORKING ON A PRESENTATION AND ARE GOING TO CONTINUE TO WORK ON IT. SO AFTER I THOUGHT ABOUT IT I WASN'T EXACTLY SURE HOW EACH FORMAT WORKS. I TOLD THEM WHAT I THINK IS THAT A CD-R WILL BE ABLE TO BE READ IN ANY CD ROM BUT THAT EVERYTIME YOU SAVE TO THE CD IT WILL MAKE A NEW AND UPDATED COPY OF THE PRESENTAION. IT WILL NOT OVERWRITE THE OLDER VERSION. IN THE CD-RW CASE IT WILL ACT LIKE A BIG FLOPPY DRIVE AND WILL ALLOW YOU TO COPY OVER THE EXISTING FILE. HOWEVER WITH CD-RW IT MUST BE FORMATTED WITH A GENERIC FILE STRUCTURE TO BE READ IN ALL CD ROMS. IF NOT THEN IT CAN ONLY BE READ IN THAT 1 PARTICULAR CD-RW DRIVE. SO AM I CORRECT IN MY EXPLAINATION AND IF NOT COULD SOMEONE PLEASE ENLIGHTEN ME AS TO WHAT THE CORRECT ANSWER IS. HOPE THIS MAKES SENSE. THANKS SLACKER

CD-R allows you to write files to a disc, but they cannot be erased. The discs can be read in basically any CD-ROM drive, allowing distribution of files to most users.
CD-RW discs are written in the same way as CD-R, but can be erased. However, you will need either a multiread CD-ROM drive, a CD-RW drive, or Windows 2000/XP in order to read the discs. Also, Adaptec released a program a while ago called UDFReader that allowed Windows 98 to read these discs in any CD-ROM drive. CD-RW discs can also be written to and erased in a similar fashion to a floppy disc if formatted to do so. Adaptec's DirectCD is the application you'd need for this.
If your co-worker is using the disc only on one PC, then CD-RW would be the best choice. Otherwise, go with CD-R as they can be read in any computer. The discs are also extremely cheap so writing multiple copies isn't very expensive at all.

There are 10 types of people in the world - those who understand binary and those who don't.

Let me see if I understand. So then what you are saying is that if he has a file saved to a CD-R and he opens it up. He modifies that particular file then when he saves it to the CD-R again it will not re-write/replace that file, instead it will put a new updated version of the file on the CD-R. SO that in the end there will be 2 versions of the file on that CD-R.
