· CDRDAO TOC Format
· CDRWIN BIN/CUE Format
· NRG Format

1 In both the 'cdrdao' and bin/cue formats there is one meta-file with
1 extensions '.toc' or '.cue' respectively and one or more files (often
1 with the extension '.bin') which contains the content of tracks. The
1 format of the track data is often interchangeable between the two
1 formats. For example, in 'libcdio''s regression tests we make use of
1 this to reduce the size of the test data and just provide alternate
1 meta-data files ('.toc' or '.cue').

1 In contrast to the first two formats, the NRG format consists of a
1 single file. This has the advantage of being a self-contained unit: in
1 the other two formats it is possible for the meta file to refer to a
1 file that can't be found. A disadvantage of the NRG format is that the
1 meta data can't be easily viewed or modified say in a text file as it
1 can be with the first two formats. In conjunction with this
1 disadvantage is another disadvantage that the format is not documented,
1 so how 'libcdio' interprets an NRG image is based on inference. It is
1 recommended that one of the other forms be used instead of NRG where
1 possible.
