This is a Copy Filled icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,800 icons, all in the same style and quality.
It's two folders, one slightly indented and they're standing perpendicular to each other. They are both rectangles, with slight triangular curves in the top right as if you're folding a piece of paper. The purpose of it is to copy anything and make a second copy of it. They both are the same size, height, and would stand up next to each other identically.
