How to open IAK file?

The main problem with MAIL.DAT Information Access Key is that the IAK file is incorrectly associated with programs. This causes the file IAK 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 IAK 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 Mail.Dat

In this case, you should first verify that the Mail.Dat application is installed on the computer. To do this, enter the name Mail.Dat into the system search engine. 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 IAK files.

Programs to open IAK file

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

Step 2. Create association of Mail.Dat with IAK files

If, despite the installed application, the IAK file does not start in the Mail.Dat application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. 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. 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 Mail.Dat application as the default for handling the IAK file.

Step 3. Update Mail.Dat to the latest version

If, despite the association of the Mail.Dat program with the MAIL.DAT Information Access Key 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 IAK file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the IAK file contents when downloading or copying. The only repair option is to download the file again.
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. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file IAK or the program directory. However, remember that not every infected IAK file can be recovered, so it is important to take care of regular backups.
Older version of IAK file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular IAK file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted IAK 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 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 IAK 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. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the IAK file for a certain period of time. If this does not work either, restart the device.
