Description
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.
A CUR file is a cursor image or animation used for the Windows mouse pointer. It may be an arrow (for general use), a spinning hourglass (for waiting periods), or an I-bar (for text editing).
