How to open CH3 file?

The main problem with Harvard Graphics DOS Chart Format is that the CH3 file is incorrectly associated with programs. This is manifested by the fact that CH3 files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the CH3 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 Harvard Graphics 98

In this case, you should first verify that the Harvard Graphics 98 application is installed on the computer. To do this, enter the name Harvard Graphics 98 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 CH3 files.

Step 2. Create association of Harvard Graphics 98 with CH3 files

However, it may happen that the application itself does not cause the CH3 file to open in the Harvard Graphics 98 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 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 select the desired program. 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 Harvard Graphics 98 application as the default for handling the CH3 file.

Step 3. Update Harvard Graphics 98 to the latest version

The fault may also lie with the Harvard Graphics 98 program, it is possible that Harvard Graphics DOS Chart Format requires a newer version of the program.

Step 4. Check for the following problems with the CH3 file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the CH3 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the CH3 file that we want to open. As a result of the scan, sometimes it is not possible to recover CH3 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of CH3 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. Some programs offer the option of recovering data from damaged CH3 files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CH3 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 CH3 to a different directory.
This problem usually affects more complex files. In this case, the CH3 file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the CH3 file while scanning. If the problem persists, restart the machine.
