# How can I view pdf, jpg and HTML files?

If you use the File Browser to navigate and double-click on it, it will automatically open with the correct application.

If you are at the command line and want to open a file, you can use:

`xpdf <filename.pdf>`

`firefox <filename.html>`

Similarly, you can use firefox for image files:

`firefox <jpg,svg, or png file name>`
