  1. List all forms in the file AudioExtractor64.exe:

    DfmExtractor.exe -i AudioExtractor64.exe -l


    Forms: 10
    Index |  Lines | Form name        | Form class
        0 |    451 | CustomizeFrm     | TCustomizeFrm
        1 |    343 | FormAbout        | TFormAbout
        2 |     49 | FormCmdLine      | TFormCmdLine
        3 |    345 | FormErrors       | TFormErrors
        4 |  1 621 | FormFileInfo     | TFormFileInfo
        5 |    474 | FormListFileEdit | TFormListFileEdit
        6 |  6 035 | FormMain         | TFormMain
        7 |    790 | FormOptions      | TFormOptions
        8 |    422 | FormProgress     | TFormProgress
        9 |    169 | FormToolsInfo    | TFormToolsInfo
  2. Save all forms from the AudioExtractor64.exe file to files with the LFM extension:

    DfmExtractor.exe -i AudioExtractor64.exe -a -e lfm


    File saved: CustomizeFrm.lfm
    File saved: FormAbout.lfm
    File saved: FormCmdLine.lfm
    File saved: FormErrors.lfm
    File saved: FormFileInfo.lfm
    File saved: FormListFileEdit.lfm
    File saved: FormMain.lfm
    File saved: FormOptions.lfm
    File saved: FormProgress.lfm
    File saved: FormToolsInfo.lfm
  3. Save form FormMain from the AudioExtractor64.exe file to main form.dfm file:

    DfmExtractor.exe -i AudioExtractor64.exe -n FormMain -o "main form.dfm"


    The form with name/class "FormMain" has been saved to file: main form.dfm

  4. Save form with index 4 from the AudioExtractor64.exe file to a DFM file:

    DfmExtractor.exe -i AudioExtractor64.exe -idx 4


    The form with index 4 has been saved to file: FormFileInfo.dfm


Tested on CodeTyphon 6.40 with FPC 3.1.1 and Laraus 1.9.0 (trunk version) with FPC 3.1.1

To compile, you need:

  1. CodeTyphon or Lazarus.
  2. JPL.CmdLineParser unit.
  3. A several Pascal units from my library JPLib.
  4. JclPeImage unit and it's dependencies from the JEDI Code Library. (All necessary JCL unit are in the jcl.7z archive in the src/jcl directory.)

How to build:

  1. Open src\DfmExtractor.ctpr file with CodeTyphon or src\DfmExtractor.lpi with Lazarus.
  2. Set build mode.
    Select menu Project -> Project Options... A new window will appear. In the tree view (on the left), select Compiler Options. At the top of this window you can select the build mode from the dropdown list. Choose: Release Win32 or Debug Win32.
  3. Build project (menu Run->Build).

Changelog / Releases

Version 1.1 (2018.02.28)

  • Project ported from Delphi to Lazarus/CodeTyphon.
  • The size of the executable file has been reduced twice.
  • Internal enhancements.

Version 1.0 (2018.01.11)
Initial release.


This program was made for my private use, but it may also be useful to someone.

When translating one program written in Delphi, I needed DFM forms to make it easier to work with the Poedit program, so I decided to write a small program to extract DFMs.


Small command line utility which allows you to extract DFM, LFM and FRM forms from executable files compiled by Delphi, Lazarus and CodeTyphon.
