What is an SWW file

SWW files mostly belong to Anno. SWW files are not a single-standard format but are used in different industries.
In most cases, these files hold save game data for the Anno series, such as Anno 1800 and Anno 1404, storing game progress and internal state details.
Other instances of SWW files carry simulation information.

Some contain HEC-RAS simulation data used in water flow modeling.

Others are outputs from ANUGA software, which simulates shallow water dynamics.

A further variant is known as a Spellswell Document, related to spaced repetition software.

To view or modify these files, use the original software that created the file. For simulation data, for example, the Surfer application is a common choice.

How do you open SWW files?

You need a suitable software like Anno to open an SWW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your SWW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SWW file directly in the browser:. Just drag the file onto this browser window and drop it.
