DfmExtractor is a specialized software utility used in reverse engineering and programming to extract user interface forms from compiled executable files. It specifically targets applications developed using Object Pascal development environments like Embarcadero/Borland Delphi, Lazarus, and CodeTyphon. Primary Purpose and Features
When these environments compile a program, the visual layout of windows, dialogs, and components is saved into metadata resource files embedded within the executable. DfmExtractor allows you to pull that layout data back out.
Supported Form Formats: It extracts .dfm (Delphi Form), .lfm (Lazarus Form), and .frm (CodeTyphon Form) files.
Portability: It is distributed as a lightweight, portable command-line tool for Windows that runs instantly without installation.
Extraction Modes: You can isolate a specific form by passing its name or index, or batch-extract every single form discovered inside the target file. Common Variations
Depending on where you encountered the term, it usually refers to one of two popular developer tools:
Jackdp’s DfmExtractor: A modern open-source command-line tool hosted on the Jackdp DfmExtractor GitHub Repository. It operates completely via terminal arguments and offers precise file output configurations.
Greatis Form Extractor: An older graphical utility provided by Greatis Software as a companion tool for their Form Designer suite. The Greatis Dfm Extractor displays a visual breakdown of the form layout, text-based DFM properties, and automatically generates boilerplate Pascal (.pas) code. What It Can and Cannot Recover
jackdp/DfmExtractor: Small command line utility which allows you to extract DFM, LFM and FRM forms from executable files compiled by Delphi, Lazarus and CodeTyphon. · GitHub
