Applies to: myViewBoard 3.0

OLF (Open Learning Format) is myViewBoard's own lesson file format. Every canvas you save in myViewBoard is stored as an .OLF file (a new file defaults to a name like untitled-1.olf), so it's the native way to keep and reopen your interactive lessons.

Cross-platform format, resolution-dependent layout

OLF was built as a common standard that works the same way on both the Windows and Android versions of myViewBoard. It also preserves the position of each object on the canvas based on the screen resolution and display ratio in use when the file was created. Layouts can shift slightly if you open a file on a differently sized display.
