There are 2 file types use the .SBP file extension:
1. Sketchbook Express iCloud Image
Image created by Sketchbook Express, a drawing, sketching, and painting iOS program; saves the state of the drawing canvas for storage in iCloud, which is Apple's file storage and sharing service.
SBP files are used for storing files in a location that can be accessed by both the desktop and iOS versions of Sketchbook. When saving an SBP file, Sketchbook Express changes the dimensions of the image so that it will fit on the iOS device's screen. Also, the number of maximum layers is reduced to six.
NOTE: Sketchbook Express has been discontinued and is no longer available.
