.SPA File Extension

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.

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.

Anritsu is a Japanese electronics equipment manufacturer that produces, among many other items, spectrum analyzers. Spectrum analyzers are used primarily to measure a signal's amplitude and frequency, to see if the signal's measurements remain within required limits. There are many different types of spectrum analyzers, some of which measure additional types of data.

Many of Anritsu's spectrum analyzers save measurements as SPA files. Users can transfer SPA files to their computer to view the measurements the files contain in Anritsu analysis programs, such as Master Software Tools.

You can open an SPA file in Anritsu Master Software Tools (Windows). Master Software Tools is a free program that comes included with Anritsu's Software Tool Box.

The SPA file is referenced by the game to illustrate splashing water, fire explosions, and other game actions. The file can also be edited to modify the appearance of the particles.
