There are two parts of the Remote File System display, Devices and Files.
Devices
Use the pull-down menu to the right of the Devices input field to display folders representing the current directory structure of the remote file system on the selected router. Click on a folder icon to specify the flash memory device on which you wish to view or modify files and to display its contents. Use the scroll bar on the right to scroll up and down the list of directories (folders).
Files
Use the pull-down menu to the right of the Files input field to display all existing files on the specified flash memory device. Use the scroll bar on the right to scroll up and down the list of files. Select a file and click the Edit button to edit it, click the Delete button to delete it, or click the left-pointing arrow button to copy it to the local file system.
At startup, only the boot flash folder and its contents are displayed. Double-click on the top-level folder to display all folders, including the config folder.
The Erase and Squeeze buttons apply to the flash file system as a whole, with no file selected.
