I didn't think I needed to go into detail but here is how the browser works with Photosync. If you need to send files to or from a PC, just connect to the wifi of that person's house, as long as they are on the same LAN, the Photosync app will create a temporary webserver and host a local website with all your photos and videos. The website address is usually just a LAN IP with a different port, just type that number into any browser in your home network and you go straight in. You are also on wifi speed so its really fast, faster than USB2 in fact if you have 802.11AC. You can browse it like dropbox, download the ones you want or drop new files in. The files save straight into the phone, you don't need to open the usb app and copy the file over.
