Methods, systems, and machine readable tangible storage media that can provide for smooth and seamless opening of a file from, for example, a preview are described. A preview of a file can be generated by a non-native viewer or reader application and in response to a command to open a file in a native application, the preview can continue to be displayed while the native application launches such that a user will perceive no interruption in display of the content. The non-native application can pass a display state (e.g. a page number or scroll position) to the native application such that the native application continues to show a user's current position or view port into the file.
