Borland Delphi form
From Just Solve the File Format Problem
The extension DFM is used by two related file formats used for describing GUI layout of Borland Delphi and Borland C++ programs. One of the formats is text-based, and the other is binary.
Standalone DFM files are found among a program's source code, and may use either of the two formats; the binary format is also found inside resources of compiled programs (resource type RCDATA).
