Imgburn and CD Text - What's the CDT file?

[Muse]

I am very into music/audio and have hundreds of CDs. My players are Pioneer PD-F1007, high capacity (301 CDs each). They support CD Text and I insist on CD Text support, so I generally copy my CDs and usually add or alter the CD Text to suit me (I find that supplied CD Text is usually inadequate for my purposes, and if there's no CD Text, I almost always supply some that suits me).

When you rip CDs with Imgburn you get 3 files:

CUE
BIN
CDT

The CUE file is a text file, the BIN has the audio. When I alter the CD Text I deal with the CUE file. The CUE file itself, when there's already CD Text on the ripped CD, at the top has a line referring to the CDT file. I need to delete that line because I don't deal with the CDT file when altering the CUE file. I then delete the CDT file before burning new CDs with my altered CD Text.

My question is, why does the CDT file even exist? I can change the CD Text just by altering the text in the CUE file? So, what's the reason for having that seemingly redundant CDT file in the first place? Am I missing something?

Well, I posted at Imgburn Forums and the response was that the CDT file is a direct dump and they do it to ensure accuracy. Seems strange, but there you go. To edit CD Text what I'm doing is the way to go. Delete the CDT file, delete the reference to it in the CUE file and make edits in the CUE file. I accomplish those edits (when there's no CD Text to begin with) with the help of a utility I wrote, it's basically a CD Text editor exterior to Imgburn itself. Of course, you can just do it by manually editing the CUE file, but that's cumbersome, but that's what I do when there's CD text already and I just want to tweak it.
