Overview of Copying and Redirecting Files

You have two options for copying or redirecting files to or from a remote FTP or TFTP server:

If you include the remote file data, the copy command contains a source and destination filename, either of which (but not both) can be remote files. The following URL format is supported for both source and destination files:

protocol://[username [:password]@]location[/directory]/filename

The location can be a hostname or an IP address.

The two versions of the URL format are as follows:

ftp://[username[:password ]@]location[/directory]/filenametftp://location[/directory]/filename

Note: The TFTP protocol does not support username and password. Entering a username and password in the TFTP version results in a command error.

The protocol specified in the command always overrides the protocol associated with the host entry, if any, in the host table. Some protocols, such as FTP, require a username and password with each request. For the URL version of the copy command, the following sequence is followed:

The location is the IP address or hostname of the remote file server. The directory/filename is the full path of the file relative to the user login root path.

The characters in the URL format can be encoded. Any of the delimiter characters can be used in the host, username, password, and directory and file fields when added as encoded characters. The encoded characters must be three characters, starting with a percent and followed by the two hexadecimal digits that are the ASCII equivalent. The system converts all printable characters before passing them to the protocol support. Unprintable characters (0-012F and 0x7f-0x7F) are not converted and are passed directly to the protocol. Printable characters (0x20– 0x7E) are decoded and all others (0x80–0xFF) are rejected.

In the following example, the username contains the @ delimiter character encoded as %40, and the directory passed to the FTP protocol layer is /dirA/dirB/dirC. The delimiter between the hostname and directory is a forward slash (/) character. To add a slash to the start of the directory specification, add the encoded slash after the host and directory delimiter.


In the following example, the directory passed to the FTP protocol layer is dirA/dirB/dirC.
