File System Overview
The Switch provides a flash file system for efficient management of the storage
devices such as flash memory. The file system offers file access and directory
management, including creating the file system, creating, deleting, modifying and
renaming a file or a directory, and opening a file.
By default, the file system requires that the user confirm before executing
commands. This prevents unwanted data loss.
In the Switches supporting XRN, the file URL must start with “unit[No.]>flash:/:”,
the [No.] is the unit ID. For example, suppose unit ID is 1, and the URL of the
“text.txt” file under the root directory must be “unit1>flash:/text.txt”.
Based on the operated objects, the file system can be divided as follows:
■
Directory operation
■
File operation
■
Storage device operation
■
Set the prompt mode of the file system
Directory Operation You can use the file system to create or delete a directory, display the current
working directory, and display the information about the files or directories under
a specified directory. You can use the following commands to perform directory
operations.
Perform the following configuration in User View.
