- The CDR file extension most commonly is an abbreviation for CorelDRAW Image File, but it may also stand for a Raw Audio-CD Data file or Crash Data Retrieval file.
- CDR image files are associated with Corel software company's programs Corel Paint Shop Pro and CorelDRAW. Audio CDR files are most commonly created by Roxio Toast CD "ripper" software, while CDR data files are unique to Bosch software's Crash Data Retrieval System.
- Each type of CDR file has a different format. Corel files store information as vector or geometric images. Roxio files are audio files, storing sound in compressed or uncompressed form and Bosch files are data files, which store information in text format.
- Two types of CDR files have corresponding formats in other programs. A CDR image file is similar to Adobe Illustrator's AI files and CDR audio files store information like AIF or WAV files.
- CDR files created by CorelDRAW or Paint Shop Pro can also be opened by ACD Systems Canvas and Adobe Illustrator. Audio CDR files can also be opened by most music player programs, including iTunes.
