The .TWSYS Folder on the MicroSD Card contains Temporary System Files necessary for the regular function of the Dash Cam.
These files serve as a backup to each individual video file. If an accident were to occur where the Dash Cam loses power these .TWSYS Files help to ensure no video files are corrupted.
When you insert a Blank SD Card into the Dash Cam it will automatically fill the SD Card with these .TWSYS Files. The Sd Card will appear full.
A lot of users are concerned that the Dash Cam will not record as the card shows as full.
These .TWSYS Files are overwritten as the Dash Cam records ensuring you will have the full SD Capacity for the Dash Cams Video Files.
These .TWSYS Files cannot be deleted or altered.
