Switching SD card and photos/videoa are out of order

[abi38]

I would like to replace my current SD card with a larger one. I copy the contents (pictures and videos only) of the old card to the new card. I plugged in the new card, and noticed that under "Camera Roll", the pictures and videos are no longer displayed according to the time taken. Somehow all pictures are shown first and all videos are at the end.

I really would like to preserve the original order. Is there a better way to copy contents from 1 card to another? I manually verified that all the files retained their original timestamp so I don't think that's the problem.

Thanks.
