This is an icon representing viewing a file. There is a rectangular piece of paper with a folded over corner in the top-right that makes a triangle. A magnifying glass covers the bottom-right portion of the paper.
This View icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
