FDF is a text file that contains information filled in active PDF form. FDF file is generated when given form is filled and exported. Please notice that FDF files are not created automatically. Form data may be exported by choosing an appropriate option from the Adobe Acrobat Reader menu.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the XFDF file after converting to FDF may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from XFDF to FDF to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting XFDF to FDF does not meet your expectations, you can simply try to find on the Internet a different version of your file in XFDF format, properly converted to a FDF file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file XFDF the desired result was not achieved, you can try to change the format of XFDF file to other than FDF. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your XFDF file converted by someone else, and the attempt to convert it to FDF on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the XFDF file in its original format (without conversion to FDF file). Such a solution will be difficult to implement, but it certainly will give the best result.
