I am not sure whether there's an official term for it (though dataphobe comes to mind, but it seems a little off), but there are a lot of minimalists when it comes to data. Probably the kinds of people that handle info that are sensitive and has to be purged frequently. Well, that or the person doesn;t really care about the files and only keeps what s/he needs.
As much as it's a goal of mine to hoard, I kinda do not have as huge as the storages of the other people here, but I tend to keep free indie games I could find, even demos sometimes, and some obscure alternative software for certain paid apps. Usual reason for the hoard is for offline use; I do not want a cloud-only environment.
If you want the bare minimum fast transfer and both PC are in local network, use Dukto-R6. It's super basic file copying, you just need to drag and drop.
For more advanced options,the others have already pointed it out.
