I have to agree that requiring the user to include the extension in the “Filename” field of the Save dialog can result in errors and isn’t super user friendly.
As I previously mentioned in a past thread (quoted at the end of this post), it seems like a waste of time to specify the extension in the filename and then specify it again in the “File Format” column. These fields have to be matched correctly and it only validates the new field text after I’ve finished editing the file name field, so when I mess up, I have to rewrite the new file name all over again. I think most Windows users are most familiar with the native file dialog which looks like the following below which allows you to write either “MyNewFile” or “MyNewFile.txt” in the filename field and the result is a file in “some-location/MyNewFile.txt”.
