How to open 4LK file?

The most common problem when using 4th Dimension Database is that a specific 4LK is not associated with the program. This causes the file 4LK to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the 4LK 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 4D SQL

In this case, you should first verify that the 4D SQL application is installed on the computer. This can be achieved by typing 4D SQL into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open 4LK files.

Programs to open 4LK file

Remember to download programs supporting 4LK files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of 4D SQL with 4LK files

However, it may happen that the application itself does not cause the 4LK file to open in the 4D SQL application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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 4D SQL application as the default for handling the 4LK file.

Step 3. Update 4D SQL to the latest version

If, despite the association of the 4D SQL program with the 4th Dimension Database 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 4D, Inc. page and install.

Step 4. Check for the following problems with the 4LK 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 4LK file. 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 virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the 4LK file that we want to open. Sometimes virus-infected 4LK files cannot be recovered, so make a backup in advance.
Older version of 4LK 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. Some programs offer the ability to automatically repair 4LK file corruption. You can restore the file from a backup or use 4D, Inc. help.
The program indicates that the file is encrypted or corrupted. The encrypted file 4LK 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. The problem is only writing to the file, not reading it. Copying the 4LK file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the 4LK file again. Some anti-virus or backup software may occupy the 4LK file for a certain period of time. If the problem persists, restart the machine.
