We sometimes see users changing a file name, unintentionally / unknowingly deleting the extension dot or removing the whole extension. After which they cannot open the document because it is no longer recognized as such, resulting in user confusion.
Where on an operating system is explicitly asked for confirmation when accidentally changing / deleting an extension.
Is there a possibility to check if there is still an extension present when editing, or else give a notification?
Example what an OS will ask you, by changing an extension.
