What is a JCR file?
Puzzle file used by nonogram puzzle programs, such as QNonograms; contains a nonogram puzzle in binary format, similar to the more common .JAP file.
A nonogram puzzle, which is similar to a griddler, paint-by-numbers, or hanjie puzzle, is a puzzle that consists of cells in a grid that must be colored or left blank in order to reveal a picture. The puzzle contains numbers for each grid row and column that indicate the number of colored square sets. You must choose which squares are colored and which squares are blank based on the numbers provided in order to solve the puzzle and reveal the image.
NOTE: The .CWD file is the same as the JCR and JAP files but contains the nonogram puzzle in plain text.
