What is a .crw file?
A .crw file is a Canon RAW (version 1.0). This one is a specialist format without an obvious everyday home.
How to open a .crw file
- The program that created it is by far the most reliable way to open it.
- On Windows, use a hex viewer or the free TrID tool to identify what the file really is.
- On Mac or Linux, running `file yourfile` in the terminal identifies most formats instantly.
The registry records this extension against Canon RAW, so software from that family is the most likely match.
How to convert a .crw file
- Identify the file first, then look for an export or Save As option in whatever program can read it.
