How to open AHTM file?

The main problem with HTML is that the AHTM file is incorrectly associated with programs. This causes the file AHTM to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the AHTM 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 Windows Notepad

An often overlooked issue is to make sure that Windows Notepad is installed on the computer. The easiest method is to use the system search engine by entering the program name Windows Notepad in it. 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 AHTM files.

Step 2. Create association of Windows Notepad with AHTM files

If the application is or has been freshly installed, but the AHTM file still does not use the Windows Notepad program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. 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. 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. Checking the "Always use the selected program ..." box will permanently associate the AHTM file with the Windows Notepad program.

Step 3. Update Windows Notepad to the latest version

If, despite the association of the Windows Notepad program with the HTML 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 Microsoft Corporation page and install.

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

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

The AHTM file may be unusually small compared to the original file. Usually this applies to AHTM files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
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. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our AHTM file. Sometimes virus-infected AHTM files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the AHTM files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair AHTM file corruption. You can restore the file from a backup or use N/A help.
The program can also signal the fact of encryption. The encrypted AHTM files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the AHTM file to another location.
This problem only occurs with more complex files. In this case, the AHTM file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file AHTM to close. Some anti-virus or backup software may occupy the AHTM file for a certain period of time. If the problem persists, restart the machine.
