This is the DAV icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
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.
