Delete all files contained on the internal NAND flash mass storage.
Unlike the “Format NAND Flash” function, this acts at a filesystem level aqnd can therefore be performed as many times as necessary.

The procedure performs the following steps:

• Calculation of the number of files contained in the internal mass storage.
• The “Searching files…” message is given.
• If zero files are found, the “No Files Found” message is given and the function ends, otherwise the “Delete <filename>” is given indicating the delection of every file found.
• Close the internal storage and end procedure
