What is an SWB file? An SWB file is a backup file created by Sketchware Pro, an app development environment available for Android devices. It contains an app development project. In addition to being used as backup files, SWB files are used to share projects with other Sketchware Pro users.

More Information Sketchware Pro is a community-maintained version of the original, discontinued Sketchware app. It allows developers to create and publish Android apps using drag-and-drop programming. While working on an app development project, developers can back up that project by selecting the three-dot menu and then selecting Backup . This saves the project as an SWB file. SWB files include everything needed to load the project in Sketchware Pro, including any custom libraries and blocks created specifically for the project. Developers often share SWB files with each other, either online or via SWB-sharing apps. For example, the app Sketchware SWB Projects allows developers to download other Sketchware Pro users' SWB files.
