UC-7420/7410 User’s Manual Managing Embedded Linux

Since different Flash disks have different sizes, it’s a good idea to check the size of your Flash disk before upgrading the firmware, or before using the disk to store your application and data files. Use the #df –hcommand to list the size of each memory block, and how much free space is available in each block.
