One's options are somewhat limited if you don't have high speed internet access where you currently are. Its one of my recurrent whinges, but we shouldn't have to rely on internet access to do something as prosaic as copy a file. Can't beat a bit of wire...
This lesson is reinforced by a recurrent need to transfer photos when I'm stood in a field in Wales, with no mobile phone signal, let alone internet access. This situation applies to far more of the country than many city dwellers realise.
My current main camera can transfer directly by wifi to another device, but a series of 85Mb RAWs is going to take a while, just as well the laptop has an SD card slot in it.
I recently video'd a performance of the 1812 overture, complete with real cannons. Just under 7Gb, I'm not uploading that!
