ISO-9660 File and Directory Naming
Standard
Each file name consists of three
components: name, extension and version number as follows: <name>.<extension>;<version>
A name or extension consists of zero or
more characters of the set [A..Z], [0..9] and _ (underscore). The version
number ranges from 1 to 32767. The name and extension together must
consist of at least one character e.g. .000;1 is a valid ISO-9660 file
name
There are three levels of interchange
defined by ISO-9660:
-
-Level 1
-
The number of characters of the name is
restricted to 8 and the number of characters of the extension is
restricted to 3.
-
-Levels 2 and 3
-
The total length of the name and
extension is restricted to 30 characters (excluding the point and
semicolon). Within GEAR the file name length is restricted to 30.
Files are listed in alphabetical order. If
two file names do not have the same number of characters the shorter name
is treated as if extended with spaces. This rule applies for both the name
and the extension. If two files have equal names the file with the highest
version numbers comes first e.g. AA.;2 before AA.;1.
A directory name consists of one or more
characters of the set [A..Z], [0..9] and _ (underscore) with a maximum of
31 characters. The maximum nesting level of directories is 8 (the root is
level 1!). The total number of characters specifying a file within a
directory (path) must be smaller than 256. Directories are sorted
alphabetically.
The order of characters is according to ISO
646, i.e. [0..9] comes before [A..Z] and [A..Z] comes before _
(underscore).
