Why warning message popup, while export recording file in Brickcom NVR remote web client playback?

In remote web client playback, when user setup the AVI path. Playback will only recognize this path to export the video file.

But if the destination has been removed or renamed, the AVI path will be invalid. NVR system would popup the warning message “An error occurred while opening the file to be exported, Error: 3" to remind the path cannot be executed.

To avoid it happens, please modified the AVI path after the path has changed.
