• Message: "TNC: Not enough memory – File system full."
• Cause: The iTNC 530 uses Flash memory. If you delete files, it leaves "holes." The system thinks it is full.
• Fix: Go to Program Run > File Manager > Special Functions > Defragmentation. Do not turn off the machine during defrag. This can take 20 minutes.
