The Files app on Windows 11 has been updated to version 3.9.14, introducing a new Signatures page in the properties window for viewing digital signatures associated with files. This feature was previously only available in File Explorer. The update also includes enhanced customization options, such as a Dual Pane setting and improved terminology for the "Add pane" action, now called "Split pane." Users can resize columns in the Column View layout and a header displaying the current search query will now appear during searches. Version 3.9.14 is currently in preview mode, and users on the stable version need to download the Files Preview app to access these new features.
