This program illustrates basic file system operations for SD/MMC and Compact Flash cards:

Mounting a drive
Determining amount of used and free file space
Creating files
Writing data
Reading data
Unmounting a drive

When the program executes it will display program status information through the debug serial port. This application has web server support for onboard flash/ram only, web pages cannot be run from external flash cards. This capability is demonstrated in the EFFS-HTTP example to illustrate the difference between the two operations.

Note: All EFFS FAT examples require that you add the Embedded Flash File System File Allocation Table (EFFS FAT) library to your project: Add a Library to a Project
