So what's a BWI file?

[spidey]

Operating System: -
Burning Software: -
Anti-virus Software: -
DAEMON Tools Version: 3.46

And how can you convert it to something DT can mount?

[Copytrooper]

You don't - bwi files are Blindwrite images, and are created with related bwt/bwa files.

[spidey]

Nope, its a single file.

And you are saying DT will never support that?

[Copytrooper]

Daemon Tools supports Blindwrite images, bwt/bwa and b5t!
Re-create the image from original cd, if you lost the bwt/bwa file(s).

[spidey]

And you know of nothing which can convert a bwi file to another format?

[Copytrooper]

No, you can't do that without the TOC file (bwt).

[spidey]

I see. Thanks for your reply.

[spidey]

Turns out IsoBuster can easily handle the file without any extra files. Now you know.

[Copytrooper]

That can work, if the file contains one track only - but for obvious reasons Daemon Tools won't support Blindwrite images without TOC file!
