A CR3 file is an image created by select Canon digital cameras, such as the EOS M50 and EOS R. It may store uncompressed RAW image data exactly how it was captured by the CCD or compressed RAW (C-RAW) image data depending on the camera setting selected. CR3 files were introduced in 2018 with the release of the Canon EOS M50, replacing .CR2 files.
DCX file is a multi-page image file developed by raster file or bitmap file formats. It is generated fro PCX files, so it has a small header that shows the .dcx then a sequence of .pcx data. Popularly used by applications to create and send multi-page fax files.
