Five Steps to Open CRW Files

If you have CRW files that you need to open, but you’re not sure how, follow these steps.


Step 1: Double-click the file.

Locate the CRW file icon and double-click it. If you have the right program installed, it should open the file automatically. If it doesn’t, move on to Step 2.

Step 2: Look for another program.

If the CRW file doesn’t open when you double-click it, you probably don’t have the right program on your computer. There are several popular programs that can be used to open a CRW file. Try one of the three most common programs: Canon Digital Camera Raw Image Format, Crossword Genius, or Cadrail Train Terrain Layout.

Step 3: Check the file type.

If none of the above programs will open your CRW file, check the file type to make sure you have a program that can open that type of file. Most CRW files are Raster Image Files, but there’s a chance it might be another type.

You can find this information in the file’s properties. On a Windows computer, just right-click the file and click properties, and look for the file type under “Type of File.” On a Mac computer, right-click the file and click “More info,” and look for the file type under “Kind.”

Step 4: Get help from a developer.

If you can’t figure out how to open a CRW file, a developer can probably tell you how. Find the program you have in the table below and contact the developer of that program.

Step 5: Find a universal file viewer.

The easiest way to open a CRW file, or any kind of file, is to use a universal file viewer like File Magic (Download). You can use it to open many different file formats. If it’s not compatible, the file will just open in binary.
