XML File Format
Gantt Designer is stored as an XML file in plain text.
While you can use a text editor to open up and view a Gantt Designer file, you are advised NOT to modify any data directly. Incompatible changes can cause data to be lost or you may bring down your PC operating system and lose other work in progress.
The XML file format will be published here once it stabilizes. With an open file format, users can be assured that their data will always be available and readable.
