What is ~DF file?

The file in the ~DF format belongs to the Developer Files category. The creator of this file is Embarcadero Technologies, Inc.. Additionally, the Developer Files category contains 1205 of other files. Delphi Form Backup appears on 1 operating systems as a functional file. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The C++ Builder application is recommended to open the file.

How to open ~DF file?

The main problem with Delphi Form Backup is that the ~DF file is incorrectly associated with programs. This is manifested by the fact that ~DF files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the ~DF file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install C++ Builder

An often overlooked issue is to make sure that C++ Builder is installed on the computer. The easiest method is to use the system search engine by entering the program name C++ Builder in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support ~DF files.

Programs to open ~DF file

Remember to download programs supporting ~DF files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of C++ Builder with ~DF files

However, it may happen that the application itself does not cause the ~DF file to open in the C++ Builder application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the C++ Builder application as the default for handling the ~DF file.

Step 3. Update C++ Builder to the latest version

If, despite the association of the C++ Builder program with the Delphi Form Backup file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Embarcadero Technologies, Inc. website or update the program from the application.

Step 4. Check for the following problems with the ~DF file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the ~DF file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our ~DF file. Sometimes virus-infected ~DF files cannot be recovered, so make a backup in advance.
Older version of ~DF file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular ~DF file corruption. You can restore the file from a backup or use Embarcadero Technologies, Inc. help.
The program can also signal the fact of encryption. The encrypted ~DF files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the ~DF file to another location.
This problem usually affects more complex files. In this case, the ~DF file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
