Overview of the File System

Overview of the File System

File System

The file system manages files and directories on storage media. In the file system, users can create, delete, modify, and rename a file or a directory, and view contents of a file.

Storage Medium

The device supports the flash memory and USB flash drive.

  • A USB flash drive is mainly used for USB-based deployment or system file loading. If the USB flash drive contains activated system software or patch software, the USB flash drive is a key component of the system and cannot be removed. The USB flash drive must use the FAT32 format. Set the format to FAT32 (format the USB flash drive) before using the USB flash drive.

  • For the AR515CGW-L, it is recommended that the Micro SD card and the USB storage device of the firewall use the ext3 file system. If the FAT system is used, the storage device may be damaged when the device is frequently powered on or off.

Naming Rules for Files

The file name is a string of 1 to 64 characters without spaces. Only names of the following files are case-sensitive:

Files in the built-in storage medium on the AR500&AR510

If names of files in the storage medium on the device are case-sensitive, you need to enter case-sensitive file names when operating the files in the FTP client view or SFTP client view.

The file name formats are as follows:
  • File name

    A file resides in the current working directory if the file name is in this format.

  • Drive + Path + File name

    This file name format uniquely identifies files in specified paths.

    In this format, drive indicates the storage medium and can be set to flash:.

    In the file name, path indicates the directory and subdirectory. The directory name is case-insensitive. Spaces and the following characters cannot be used in the directory name: ~ * / \ : ' "

    Paths are either absolute or relative.
    • flash:/my/test/ is an absolute path.

    • /selftest/ is related to the root directory and indicates the selftest directory in the root directory.

    • selftest/ is related to the current working directory and indicates the selftest directory in the current working directory.

    For example, in the dir flash:/my/test/mytest.txt command, flash:/my/test/ is an absolute path.

    Run the dir test/mytest.txt command to find the mytest.txt file from a directory related to the current working directory (flash:/my/ for example).

    • In the file operation command format, filename indicates the file name.

    • In the file operation command format, directory indicates the path (drive + path).
