Every now and then someone asks what's the best way to transfer files, documents, photos from their phone to their desktop PC (this one works both ways). My definition of best means no cables, few screen taps and over Wi-Fi. I walk into the room where the PC is running, I want to quickly transfer the 5 photos I took earlier, go to Gallery, Album, select images, then tap on Share ... choose Add to Sync, transfers begin immediately and within seconds the image appears on my desktop. Similarly, you drag and drop a file to the designated folder on the desktop and the file appears on the phone app. So convenient and no fuss. Oh, it's free too with no ads: https://getsync.com/
