I have (2) Tapo C120 cameras  (hw ver 1.6 on both camera boxes) purchased between Sept 2024 and Feb 2025, both with the maximum external SD memory supported. I just removed the external memory SD's from both cameras and both memory cards show well over 1,000 invalid MP4 files written at 262,144 kB per file. There are also some valid video files on the same memory. I am alarmed that this sort of file writing bug exists that fills up my security camera external memory and risks the chance of overwriting my security video files.

I have a Word docx that shows a partial directory excerpt of one of the SD cards file contents, but couldn't see how to attach it. I must have your s/w engineering department fix this as soon as possible.
