I upgraded to a new phone so was transferring whatsapp folder to the new phone. Normally i transfer the whats app folder to a sd card then transfer it to the new phone.This usually takes about 30 mins, this time its taking too long 6-7 hours and then i get a message that there isnt enough memory in the card when the card has 10 gb free and the whatsapp folder is 5gb. I also tried using Gdrive this would have taken 4-5 days it was very slow.
