What should I check when a file opens in the wrong app?
Check the file extension and the app currently associated with it. Changing the default for a file type affects other files of that type as well. If you only need a one-time choice, use the file's Open with option instead.
Will changing the default convert my files?
No. It changes which app opens them, not their format or contents. Test one representative file after the change. If the chosen app cannot read the format, select a compatible app rather than renaming file extensions.
