It seems the name of video and photo all in a format as DJI_XXXX, always four digital, what will happen when the number reach 9999? Will it keep going or back to 0000? How could I reset the number right now?

Hi, Thank you for reaching out and we do apologize for the inconvenience. The file numbering scheme was designed by our developers. Every time the device will save a file, it will follow that numbering scheme. However, we can forward this concern to our designated department for attention. Thank you for your kind and understanding. Cheers!
