In computing, a file dialog (also called File Selector/Chooser, file requester, or open and save dialog) is a dialog box-type graphical control element that allows users to choose a file from the file system. File dialogs differ from file managers as they are not intended for file management (although some offer simple operations such as folder creation), rather they are intended for the opening and saving of files. Before file dialogs, most programs requested files as a command line argument or as an exact file path. Others required users to select a file from the file manager. A file dialog allows an application to access individual files in a standardized and secure way, with the user in control of what files to share with the application.
