How to open XMCF file?

An often recurring problem with FileMaker Custom Function Format is that XMCF is not associated with the correct program file. This causes the file XMCF to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the XMCF 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 FileMaker Pro

In this case, you should first verify that the FileMaker Pro application is installed on the computer. The easiest method is to use the system search engine by entering the program name FileMaker Pro in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file XMCF with FileMaker Pro. Later in this article you will find a list of programs that can open XMCF files.

Programs to open XMCF file

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

Step 2. Create association of FileMaker Pro with XMCF files

If the application is or has been freshly installed, but the XMCF file still does not use the FileMaker Pro program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the XMCF file with the FileMaker Pro application.

Step 3. Update FileMaker Pro to the latest version

If, despite the association of the FileMaker Pro program with the FileMaker Custom Function Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the FileMaker, Inc. page and install.

Step 4. Check for the following problems with the XMCF file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. Usually this applies to XMCF files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the XMCF file that we want to open. However, remember that not every infected XMCF file can be recovered, so it is important to take care of regular backups.
Older version of XMCF file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular XMCF file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file XMCF except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the XMCF file to another location will fix the problem.
This problem only occurs with more complex files. In this case, the XMCF file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the XMCF file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
