How to open ABNF file?

The most common problem when using JCard To VCard Data Format is that a specific ABNF is not associated with the program. Thus, when you open ABNF, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ABNF 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 jcard-to-vcard

An often overlooked issue is to make sure that jcard-to-vcard is installed on the computer. The easiest method is to use the system search engine by entering the program name jcard-to-vcard 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 ABNF files.

Programs to open ABNF file

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

Step 2. Create association of jcard-to-vcard with ABNF files

If, despite the installed application, the ABNF file does not start in the jcard-to-vcard application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. 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 ABNF file with the jcard-to-vcard application.

Step 3. Update jcard-to-vcard to the latest version

If, despite the association of the jcard-to-vcard program with the JCard To VCard Data Format file, the file still does not open, check the program version and possibly update it to the newest version.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The ABNF file may be unusually small compared to the original file. This suggests truncating the ABNF file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the ABNF file that we want to open. However, remember that not every infected ABNF file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the ABNF files changes over time. 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.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged ABNF files.
The program can also signal the fact of encryption. The encrypted file ABNF 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the ABNF file to another location will fix the problem.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file ABNF to close. However, some background programs may block the ABNF file while scanning. If nothing helps, please reset the device.
