How to open HND file?

The most common problem when using HNSKY Deep Sky Database is that a specific HND is not associated with the program. Thus, when you open HND, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the HND 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 HNSKY

The first step is to check if the computer has the HNSKY program installed. This can be achieved by typing HNSKY 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. Below is a list of programs that support the file HND.

Step 2. Create association of HNSKY with HND files

However, it may happen that the application itself does not cause the HND file to open in the HNSKY 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. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the HND file with the HNSKY application.

Step 3. Update HNSKY to the latest version

If, despite the association of the HNSKY program with the HNSKY Deep Sky 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 Han Kleijn page and install.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The HND file may be unusually small compared to the original file. This is most often caused by a problem while downloading the HND file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file HND or the program directory. However, remember that not every infected HND 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 HND 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 this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular HND file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Han Kleijn
The program indicates that the file is encrypted or corrupted. The encrypted HND files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move HND to a different directory.
This problem usually affects more complex files. In this case, the HND 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 HND 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.
