Description:

Filenames in Unix.

Class protocol:

 isBadCharacter: aCharacter

 isCaseSensitive

return true, if filenames are case sensitive.return true, if filenames are case sensitive.

 nullFilename

(there may be more in the future.

 separator

 separatorString

Instance protocol:

 fileType

this returns a string describing the type of contents of
the file. This is done using the unix 'file' command,
(which usually is configurable by /etc/magic).
Warning:
Since the returned string differs among systems (and language settings),
it is only useful for user-information;
NOT as a tag to be used by a program.

 isExplicitRelative

return true, if this name is an explicit relative name
(i.e. starts with './' or '../', to avoid path-prepending)

 isHidden

return true, if the receiver represents a hidden file.
On UNIX, a name starting with a period is considered hidden.

 isImplicit

return true, if the receiver represents builtin names such as '.' or '..'.
On UNIX, the current and parent dir names are considered implicit.

 osNameForDirectory

internal - return the OS's name for the receiver to
access it as a directory.

 osNameForFile

internal - return the OS's name for the receiver to
access it as a file.
