This is a DAV 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 12,600 icons, all in the same style and quality.
It's a logo for the website webdav.org. Which stands for: Web-based Distributed Authoring and Versioning. A set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers. The logo are the letters D A V, in black outlined, block letters, white on the inside, each letter up against the other touching.
