Wpath/directory/CJ
|
Dir•path/directory/
]
The directory’s name must be composed
of alphanumeric characters and may
include the minus sign (hyphen, -) and the
colon (:). The first character must be a letter.
Case does not matter. No blank or space
characters are permitted in the name.
Include the full path, not just the name of
the directory. Nonalphanumeric characters
in the path (for example, /) must be
encoded to hex. characters for use with a
Web browser.
N
A directory does not fully exist until a file has been copied into that path. Also, the IPL T S unit operates differently from PC operating systems: files stored in and directories created
in the IPL T S device may have the same names.
Example:
E
majordirectory/subdirectory/next-level/CJ
}
Wmajordirectory %2F subdirectory %2F next-level %2F CJ
|
Dir•majordirectory/subdirectory/next-level/
]
In this case, the path is majordirectory/
subdirectory/. The directory that was just
created or changed to is called next-level.
Example:
E
custompages/HTMLfiles/CJ
}
Wcustompages%2F HTMLfiles%2FCJ
|
This example just created a subdirectory for
storing the user’s custom-made HTML files.
The directory that was just created is called
HTMLfiles.
