I have a CD image which is in .cdr format. (Please note, it's not the same as a Corel Draw image - which also uses the .CDR extension).

Is there any way to open it on Ubuntu? I don't have a local CD drive - I just want to extract the contents to my HDD.

It won't open with Brasero, I can't mount it, nor extract it from the file manager.

Is there any way to convert it to a standard ISO?

  • I can not check it right now, but did you try simply renaming a .cdr file to an .iso and them mount? Sep 3, 2014 at 8:35
  • I did try that - sadly, it just says that it's not a valid image. Sep 3, 2014 at 8:37

Test this:

Given that Gnu/Linux has losetup which you can use to attach a file to the system as a block device.

You may be able to mount the image.cdr, with the following command:

sudo losetup /dev/loop0 image.cdr

Now you can use the image like a real cd.

CDR could be RAW Audio CD. Import it into Audacity via File -> Import -> Raw Data and setup appropriate settings.

Well, I found one way to do it.

The disc was, apparently, an audio recording. By using avconv / ffmpeg, I was able to extract the raw contents.

avconv -i image.cdr

Tells me the codec etc. Then, to extract:

avconv -i image.cdr -acodec copy output.mkv
