Hi Jean-Luc, as I mentioned to you over email, if you click Keep SketchBook in the dialog that pops up to warn you about this extension conflict, Pixelmator Pro will automatically switch to saving PXD files in package format. If, after you remove Autodesk SketchBook from your Mac, you still have issues opening files in Pixelmator Pro, feel free to reach out to our support team at Quote In short, there are some compatibility issues with the SketchBook app and Pixelmator Pro files - you can remove the app and these should be cleared up, or keep the app, and we’ll save Pixelmator Pro files in package format. Package files do, however, work perfectly with iCloud. However, the package format isn’t natively supported by many cloud storage providers, in which case Pixelmator Pro files are interpreted to be folders.

If you still use SketchBook and would prefer to keep it around, instead of saving Pixelmator Pro files in binary format, we’ll use the package format. Since SketchBook is no longer supported by Autodesk, we assume that most users have moved their workflows to other apps and would be fine removing SketchBook, if it fixes these compatibility issues. If you try to open Pixelmator Pro files on a device that has the Autodesk SketchBook app installed, or has some of its internal files left over, you’ll see the “Autodesk SketchBook App Detected” alert. This causes macOS to be unable to recognize Pixelmator Pro’s PXD files as Pixelmator Pro files when these are in binary, rather than package format. SketchBook supports Autodesk Pixlr files, which use the same extension.
