Hi,

I've got a question here. This is a very new thing for me. I wonder if anyone has heard of UDF. I think it stands for Universal Disc Format.

What happened is i have a few PDF files and i was asked to save them onto a CD. since i have got a rewritable CD-ROM, i said i could do that for them.

After writing all the pdf files onto the CD and gave it to them, SURPRISINGLY they're unable to open it because the files were in an udfreader format.

Is this a very common problem with CD?

I wonder How to open the files then.

By the way, i'm running windows XP Pro.

THANK you very much in advanceAssociates:

UDF = Universal Disk Format.  It's a relatively new file system created by the Optical Storage Technology Association.  Standard CD-ROM drives, drivers, or operating systems such as DOS cannot read UDF-formatted discs.  Recordable drives can read them.

Most standard CD drives in service today can in fact readily read UDF formatted disks. What usually happens when a UDF disk is INSERTED into an unprepared system is that the UDF reader installer autoruns. If autorun is disabled, the installer appears as the root of the CD.
However, it's much better practice to USE the CDRW as a normal CDR and then erase it when needed again. If you're using XP, the inbuilt CD burning service via Explorer is excellent for this.Backdated:

Right, what i meant is Windows OSes cannot read UDF-formatted discs natively and require drivers to read them.

 Thank you, PCdoc4christ and Backdated for your support.

I've never known about this before but i see now.

Thank you for sharing your info with me.

BTW, if the OS doesnot support it, what sort of driver do i need to be able to read it? if there is, can i download it from the net?

Thank you in advanceIt's not the OS that needs to support UDF; it's the drive unit itself. However:
