Loading and saving project files
Users can save an UNDO project or load existing project files from the main menu located on the UNDO tool command bar (Figure 3-3). The UNDO tool files are saved with the file extension of ".undo". The files are JSON file format and generally quite small in size so they can be emailed or sent to other users or decision-making authorities when required. It is important to note that saved files may only be compatible with a current version of the UNDO tool, and users are encouraged to print reports of the development areas so that information is not lost if an updated version of the tool is released. Users on the UNDO tool email list will be notified of upcoming releases and given warning to save the information as reports before the .undo files become redundant.
If the UNDO tool has been installed as an app (Progressive Web App) in the user's device, double-clicking on the .undo file will launch the UNDO tool app and load the file. This feature is experimental on desktop Chromium-based browsers such as Google Chrome and Microsoft Edge. For this to work, the .undo file will need to associated with the UNDO tool app once it is installed.
