Transferring a large amount of files.

If by somewhere you mean another destination, same person, it's probably best to get an external hard disk for backup/transfer purposes. There are a lot of options out there. Choosing this route is good since it's a handy tool for transfer, as well as acting as backup source in case your hard drive fails and you have no backup anywhere else. Recovering and cloning to a new drive is easy as heck too. This is an investment I deem to be necessary.

If it's a one-time project, you could split zip/rar archives and host them on megaupload, fireshare, etc. I would just get an external drive though.
