What is a .DFM file?

DFM files are form files used by Delphi and C++Builder to define the appearance and behavior of an application's user interface. They store form information, including windows, buttons, menus, text fields, and other controls that appear when a program runs, along with their properties and settings. DFM files can be stored in either a text-based or binary format, depending on the development environment and project settings.

If you work with Delphi or C++Builder projects, you may encounter DFM files alongside source code files, such as PAS and CPP files. They are commonly found in application project folders, inherited from older Windows software projects, or accessed when maintaining or modifying existing Delphi applications. File Viewer Plus can open DFM files, allowing you to view their contents and edit and save the text-based source data.
