Date updated: October 22, 2026
Record marked as obsolete and not updated for a long time.
The cng file extension identifies image files encoded in a format associated with applications developed by Priority Software. These files contain bitmap image data.
It seems Priority Software is no longer in business, and the current usage of this format is unclear. Support in current image software may therefore be limited.
The original Priority Software application that created the file may be needed to open this obsolete format. Support in current image viewers is unclear.
If the original Priority Software application can open the file, use its export or save-as function to create a standard bitmap image.
