Systems and methods for seamless access, editing, creating of files in a web or mobile interface to a collaborative cloud platform (e.g., cloud-based file sharing, collaboration and/or storage service) are disclosed herein. In one embodiment, a file accessed through the web or mobile interface is associated with an “Edit” button/action, or other similar feature. When selected, if an editor or other native application to edit or access the file is not installed, this action can automatically launch the installer and prompt the user to install the editor. If it is installed, this action can launch the native application on the user's computer.
