(OP here)
WOW, didn't expect a heated conversation when I posted this
So first, thanks everyone for trying to help. The reason I didn't come back was that I didn't get any notice that you all replied to me
I do have some experience with code and linux, so I may try some of your suggestions here, but as some of you also said, I think I will try to use FolderSync first to see if it does what I want to do. If it does I may create a macro to run it.
Basically, it is for backing up images and videos from my daughter's phone, to the SD card. the phone itself is not so stable lately and I don't want her to loose to many of her files if it dies one day. and I prefer to copy and not move the files to the SD because SDs also may day any day
So again, thanks everyone. I 'll be back here if I need some more help from you!
