DVI is the acronym for the Device Independent file format, which is the output file format for documents written in LaTeX. These files are essentially binary files. LaTeX file.Tex creates this file. To see the .DVI file on the Windows platform, download and installation of MiKTex is a must. Once the procedure of the installation is complete, double clicking the DVI file and it will open it.
DVI is a file format similar to PDF, often created using LaTex. DVI stands for Device Independent.
Once using Windows, you can install MiKTeX, which includes software for viewing DVI, and LaTeX itself (which you can also use to convert TeX files (.tex) to DVI). MiKTeX is free.
Once installed, simply double-click a DVI file to view it.
