The b _ _ ch is iPhone tends to casually and with no rime or reason create countless folders with obscure folder names, that you have to wade thru to find the video. On a Windows PC, you cannot see the folder creation dates, nor do the folders get setup with videos in obvious places.
I just had to do this on my wife's iPhone 6 and had to search thru 30 or so folders. HUGE PITA !.
