What is a DDF file?
A DDF file is a plain text file that contains compression and packaging instructions for creating a Windows Cabinet archive (.CAB file) with the Microsoft Makecab utility. It stores various properties, including which files to include in the CAB archive and the compression settings to apply. DDF files are only meant for instructional purposes, acting as a guide during the packaging process, and are not embedded within the final CAB file.
More Information
Makecab is available on Windows Server 2012, 2012 R2, 2016, 2019, and 2022. Developers or system administrators distributing Windows applications and drivers as CAB files with Makecab typically create and manage DDF files.
How to open a DDF file
You can create CAB archives based on DDF files with Microsoft MakeCab.
You can also open DDF files with a plain text editor to view or edit them. However, be careful when modifying information in DDF files since improperly editing the files may lead to issues with the compression process or compatibility with apps that support CAB files.
