Additional Description
Directory commands
Change to
or create a
directory E
path/directory/ CJ
}
W path %2F directory %2F 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 are not permitted in the Web browser.
N A directory does not fully exist until a file has been copied into that path. Also, the IPI operates differently from PC operating
systems: files stored in and directories created in the IPI may have the same names.
Example 1: E
majordirectory/subdirectory/next-level/ CJ
}
W majordirectory %2F subdirectory %2F next-level %2F CJ
|
Dir•majordirectory/subdirectory/next-level/
]
Example 2: E
custompages/HTMLfiles/ CJ
}
W custompages %2F HTMLfiles %2F CJ
|
Dir•custompages/HTMLfiles/
]
Example 3: E
oak/CJ
}
W oak %2F CJ
|
Dir• oak
]
In example 1, the path is majordirectory/subdirectory/. The command created or moved to a directory called next-level.
In example 2, a directory called HTMLfiles was created inside the custompages directory.
In example 3, the user moved to a directory called oak.

N The current directory is determined on a per-connection basis. At the beginning of each IP connection/session, the current
directory is selected as the root directory.
N Directory = A text string drawn from the alphabet (A~Z), digits (0~9), minus sign/hyphen (-), plus sign (+), or colon (:). No
blank or space characters are permitted as part of a name. No distinction is made between upper and lower case. The first character
must be an alpha character. A directory does not truly exist until a file has been copied into that path. Unlike various PC operating
systems, a File and Directory on the Extron product are allowed to have the same name. The current directoy is a per-connection
setting. It begins at the root for each new IP session.

N Updating firmware can be done by loading an .S19 file with this command. If the box determines that the .S19 file is not intended
for this product, the “Upl

” response is followed by an “Fwm

” response (Firmware mismatch).
