More info

If you fill out such a pdf file, you can only print it out with the Acrobat Reader, because the Acrobat Reader can load form data, which exists as a FDF file, but can not normally save it.

However, the creator of a form may provide the option to submit the form data to a form server, for example, with an FDF Toolkit application, or have it stored locally. In this way you do not need to transfer the entire pdf file, just the actual data. This is mainly used in automated form data processing.

Other pdf display programs, for example pdf-Xchange, offer the possibility to directly save or load FDF files and thus to fill in a form or to save the data locally.
