There are many possible solutions for this. This is Android, after all! The simplest solution, imo, is to install a free 'cloud app' – like Dropbox or MEGA – on both the phone and the PC(s). Any file(s) you chuck into that cloud on either device is then automagically available on the other one too. No proximity or (fidgeting with) cables required. You can do it from a thousand miles away.
OR, once it's in your cloud you can copy the public downloadlink to it and send that link to whoever you like. (This is my preferred m.o. when I'm mobile/not on WiFi, because it doesn't eat whole chunks out of my monthly dataplan as files, photos, and videos do; just mere KBs; and I can still 'send' hi-resolution stuff = big files).
Dropbox (= giant Google; US-based) gives you 5GB of free storage space, works like a charm, and is tightly monitored by the NSA. MEGA (= Kim Dotcom c.s.; New Zealand-based) gives you 50GB of free securely encrypted storage space, works in any device's web browser (although Chrome is preferred), and canNOT be monitored by the NSA!
There are good free Android apps for both in the Play Store.
