Disk Full Warning Overview

This feature provides event logs and automated actions when the remaining space on a connected USB Flash Drive falls below a user-defined threshold.

Key Behavior:

• Threshold criteria: Based on remaining space (not total capacity).
• Additional option can be applied that automatically removes the oldest file when hitting the threshold.
