PRV file extension is used for storing document files created with E-on Vue spatial modeling software. PRV file allows users to preview created 3D scenes. Files saved in PRV format are generally small in size due to the type of data thay contain.

PRV files, in contrast to the final image, store lower resolution and less detailed images. Main purpose of PRV file is to offer image preview and allow users to correct errors and mistakes before final, and often time-consumming, rendering process.
