CRW is the file extension for Canon RAW file format. CRW is the name of this unprocessed and uncompressed RAW file format that Canon uses for its digital cameras. The Canon RAW file format is based on the CIFF (Camera Image File Format) format. Its structure is very similar TIFF’s in the sense that its directories point to data within the file. The only difference is that whereas TIFF’s offsets are absolute, CRW’s are at the beginning of the data block for each directory.
