Camera RawX FAQ

1. My RAW file is not supported by Camera RawX

• If your camera's RAW file is not supported by Camera RawX, please email us so that we can add the file extension support in a future release.
• Current supported RAW files are: Adobe DNG, Canon (.CR2, .CR3 files), Fujifilm (including compressed RAF files), Nikon (including HE/HE* lossless compressed NEF files), Olympus, Panasonic, Sigma Foveon X3F, and Sony (.ARW and .ARQ).
• Camera RawX has been tested with macOS Sequoia 15.3.1, 15.4 and all functions performed accordingly. If it does not work for you, please contact us for help.

2. Thumbnails are not showing up in existing folders

It is possible the QuickLook cache believes that the thumbnails are up-to-date and does not call Camera RawX to generate a new thumbnail, but provides the thumbnail from the cache instead. If you see thumbnails being generated in a new folder, but generic thumbnails are presented in an existing folder, you will need to clear the QuickLook cache.

Open the Terminal app, and type the following:

qlmanage -r

qlmanage -r cache

Then reboot your Mac so Finder regenerates the thumbnails. On recent versions of macOS, restarting Finder alone is no longer enough — a full reboot is required.

3. Thumbnails are not showing up for Sigma Foveon .X3F RAW files

Fixed in Camera RawX 2.4.0. Update from the Mac App Store and X3F thumbnails will render correctly, even with Sigma Photo Pro installed.

If you were previously affected, you may also need to clear the QuickLook cache (see section 2 above) so Finder regenerates the thumbnails.
