Your smartphone is a powerful computer in your pocket — and with Android, part of that PC-like muscle means being able to plug your phone into any Windows or Mac system and drag and drop files either way.
Unlike iPhones, Android devices allow you to access their file systems directly, without the need for any cumbersome interfaces or complicated procedures. In fact, transferring files to or from an Android device is basically no different than plugging an external hard drive into your computer and moving data to or from it.
All you need is your phone, your computer and a cable to connect 'em — with micro-USB or USB-C on the phone side and USB-A or USB-C on the computer side, depending on the specifics of your devices. (Most newer high-end Android phones use USB-C, whereas most pre-2016 devices and many current budget-level phones have the older micro-USB standard. USB-A, meanwhile, is the traditional connector port you're used to seeing on computers, while some newer models like Apple's latest MacBooks have USB-C.) There's a decent chance that the same cable that connects your phone to its wall charger will work.
