/*
If there are no external programs, such as error checking, etc., DIC outputs
a slightly different set of files. This reduced set needs to be documented in
order for special use cases, such as self-built versions of DIC or removed
helper programs, can be detected to the best of our ability. Below is the list
of files that are generated in that case:
.bin
.c2
.ccd
.cue
.img/.imgtmp
.scm/.scmtmp
.sub/.subtmp
_cmd.txt (formerly)
_img.cue
This list needs to be translated into the minimum viable set of information
such that things like error checking can be passed back as a flag, or some
similar method.
Here are some notes about the various output files and what they represent:
- bin - Final split output disc image (CD/GD only)
- c2 - Represents each byte per sector as one bit; 0 means no error, 1 means error
- c2Error - Human-readable version of `c2`; only errors are printed
- ccd - CloneCD control file referencing the `img` file
- cmd - Represents the commandline that was run
- cue - CDRWIN cuesheet referencing the `bin` file(s)
- dat - Logiqx datfile referencing the `bin` file(s)
- disc - Disc metadata and information
- drive - Drive metadata and information
- img - CloneCD output disc image (CD/GD only)
- img.cue - CDRWIN cuesheet referencing the `img` file
- img_EdcEcc - ECC check output as run on the `img` file
- iso - Final output disc image (DVD/BD only)
- mainError - Read, drive, or system errors
- mainInfo - ISOBuster-formatted sector information
- scm - Scrambled disc image
- sub - Binary subchannel data as read from the disc
- subError - Subchannel read errors
- subInfo - Subchannel informational messages
- subIntention - Subchannel intentional error information
- subReadable - Human-readable version of `sub`
- toc - Binary representation of the table of contents
- volDesc - Volume descriptor information
