With my U1000, it records to several locations on the SD card based on the recording mode.
During normal driving it is continuously recording, and saves files to the Cont_Rec folder. Most of my recordings are out here. During normal driving if it detects an impact, such as an accident, it saves to Evt_Rec. These would be useful when providing info to insurance companies after a colllision. If I push the manual record button to save something worth finding later, it saves to Manual_Rec.
Regarding setting up the parking mode, the camera is always on, but only saves files to the SD card depending on what your settings are. If motion is detected it can save to motion_timelapse_rec, and if impact is also detected it saves to parking_rec.
You can also set a time lapse recording mode for parking where no impact is detected and it will save to motion_timelapse_rec, or where an impact is detected and it is saved to parking_rec.
Your complaint is that the camera is saving additional footage that you don’t desire. However, only files in Evt_Rec, manual_rec, and parking_rec are protected. All other files in cont_rec and motion_timelapse_rec are automatically overwritten on a rolling basis. That is, as the card fills up, it overwrites the oldest files first.
If an incident occurs to your vehicle while driving or while parked, you can go back and look at the saves footage to see what happened and provide info to others as proof. All other recordings are useless and will be erased as space is needed. If you’re concerned that too much is being recorded you don’t need to buy a different camera or set a zone to ignore, you can just buy a larger SD card. The 32 GB or 64GB card that comes with the camera (depending on your market) is really too small anyway.
