What is MHTM file?

The MHTM file has been categorized as Web Files. Web Files consists of 303 similar files. Mime HTML (MHTML) is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others. The Microsoft Internet Explorer application is recommended to open the file. It was released by Microsoft Corporation. There are also 2 alternative programs to handle the MHTM file. Mozilla Firefox, Opera browser will apply when it is not possible to use Microsoft Internet Explorer.

How to open MHTM file?

The main problem with Mime HTML (MHTML) is that the MHTM file is incorrectly associated with programs. Thus, when you open MHTM, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MHTM 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 Microsoft Internet Explorer

An often overlooked issue is to make sure that Microsoft Internet Explorer is installed on the computer. To do this, enter the name Microsoft Internet Explorer into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open MHTM files.

Step 2. Create association of Microsoft Internet Explorer with MHTM files

If, despite the installed application, the MHTM file does not start in the Microsoft Internet Explorer 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. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. 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 MHTM file with the Microsoft Internet Explorer program.

Step 3. Update Microsoft Internet Explorer to the latest version

If, despite the association of the Microsoft Internet Explorer program with the Mime HTML (MHTML) 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 MHTM file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the MHTM file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the MHTM file that we want to open. Sometimes virus-infected MHTM 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 MHTM files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged MHTM files. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted MHTM 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. The problem is only writing to the file, not reading it. Copying the MHTM file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the MHTM 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 MHTM file while scanning. If this does not work either, restart the device.
