Is there any other way please?

Hi to all, please, is there any other way how to transfer voice memos to my desktop/laptop without using a cable? I know it is possible to do it by e-mail, but I do not think it is possible in my case as I record my lectures mostly which are more than two hours long, so the file would be quite big for e-mail to come through. Another option I have heard of is Dropvox, but it says something like it streams voice memos at time while being recorded. Not sure if that option is good for me because wifi at school is not that reliable sometimes. If anyone knows about anything, please let me know. Your help would be highly appreciated. Thank you in advance.
