What is an SPA file?

A SPA file is a Zip-compressed application used by the Spotify desktop app. It contains component files, including .CSS, .HTML, .JSON, and .JS files, used to load and display a feature (such as Browse, About, or Follow) in Spotify. SPA files are found in Spotify's Apps folder.

More Information

Spotify is an audio streaming service that allows listeners to search for and play any of over 60 million songs and podcasts. Listeners can also create their own Spotify playlists and share them with others or rely on Spotify's recommendations to play a radio-like stream of songs.

While most people listen to Spotify via the service's mobile apps, Spotify also offers a desktop application that Mac and Windows users can download and use to listen to audio on their PCs. To show features to listeners, the Spotify desktop app references a series of SPA files that are saved in the app's Apps folder.

For example, if you navigate to Spotify's Apps folder, you'll see a file named browse.spa. When you click the Spotify desktop app's Browse button, Spotify accesses browse.spa and uses it to load the Browse feature. (You can also access the Browse feature by searching for spotify:browse in Spotify's search bar, which causes the app to access browse.spa.)

Each SPA file is a Zip-compressed file that contains a series of other files. These component files are used to properly load and display each SPA file's associated feature. For example, if you rename about.spa to about.zip, decompress it, and open the about folder that appears, you'll find the set of files used to show the Spotify desktop app's About Spotify window.

How do I open an SPA file?

Spotify SPA files are not meant to be opened. However, if you want to view the files contained within a SPA file, you can rename the file to use the .ZIP extension, decompress it, and view its contents as you would any Zip archive.

Also, you can open some SPA files in Spotify by searching for spotify:filename in the Spotify desktop app's search bar. For example, you can open the About Spotify window by searching for spotify:about, and you can open the Browse feature by searching for spotify:browse.
