About CDI

Padus made DiscJuggler, a CD burner for Windows whose .cdi images keep a whole disc, every session and track, in one file. They were a favorite for discs with several sessions, which most other images can't hold.

A CDI is the tracks' sectors one after another, 2,048, 2,336 or 2,352 bytes each, with a table at the end that lists the sessions and their tracks, its version in the last bytes. Music tracks are CD sound, 44.1 kHz stereo.

Filepeek reads that table and the sectors itself. Each data track opens as a folder, the last session's first, since that's the one a drive reads, and audio tracks play as songs in the audio player. Save as ISO turns a data track into an ISO, and each song saves as MP3 or WAV.

Questions

How do I open a CDI file?

Drop it on this page or choose Peek a CDI. Data tracks open as folders, audio tracks as songs, with nothing to install.

What about discs with several sessions?

Each session is listed with its tracks, and the data track of the last one, the one a drive reads, opens first.

Can I turn it into an ISO?

Yes. Choose Export, then Save as ISO, and the data track is saved as a plain ISO, which any computer opens.

Can I play its music?

Yes. Each audio track plays in the audio player, and Export saves each one as MP3 or WAV, or every track in one ZIP.

Is my image uploaded?

No. It opens inside your browser and never leaves your device, however big it is.
