Roger, I believe it's an image file which, as Andrew says, you burn to a CD. There is an option to copy an image file on Easy CD Creator and probably on Nero as well and I know these ISO files have to be copied this way, for example, when you want to use the CD to update the PTR1. I hope this might help a bit. I struggled to understand this one also and got very short responses when I tried to find out how to create the image ready for updating the PTR1. I'm afraid I don't have Easy CD Creator loaded on my new machine yet so can't verify the option for you, but I guess this should be sufficient now. -- Carol ----- Original Message ----- From: "Andrew Hodgson" <andrew@xxxxxxxxxxxxxxxxx> To: <access-uk@xxxxxxxxxxxxx> Sent: Thursday, May 27, 2004 6:12 PM Subject: [access-uk] Re: File Types > Hi, > > You burn it to aCD using a CD burning program. > > Andrew.=20 > > > -----Original Message----- > > From: access-uk-bounce@xxxxxxxxxxxxx=20 > > [mailto:access-uk-bounce@xxxxxxxxxxxxx] On Behalf Of Roger South > > Sent: 25 May 2004 22:24 > > To: access-uk@xxxxxxxxxxxxx > > Subject: [access-uk] File Types > >=20 > > Hi All > >=20 > > I've downloaded a file from my file sharing program and it is=20 > > a ISO type > > file.
