Mime MHTML Format | N/A | Web Files |
The file extension .MHTML stands for MIME HTML (Multi-purpose Internet Mail Extension HTML) and is used for webpages that are stored as a single file. The file type commonly referred to as an “mhtml” or “mht” file, is a web page archive format which is used to combine resources (such as HTML, images, CSS, audio and video) into a single file. This way the files are sent together in one document and can still be viewed and interacted with like normal webpages. They are frequently used by email programs such as Microsoft Outlook, however Mozilla Thunderbird and other programs can also work with.mhtml files.
The Benefits of MHTML Files
MHTML files are particularly helpful when you want to save a webpage for archiving or later reference as they can capture rich media files which would not be connected to the page otherwise. They save each page as an individual file, negating the need for web browsers to request multiple files from a webserver when a single webpage is loaded. In addition, these files cannot be edited in a standard text editor so their contents will remain largely unchanged. MIME files are also useful when testing emails since the environment will be consistent each time.
Similar File Extensions
Other web archiving formats similar to.mhtml include .MHT, MHTL, EBA, and .EML.
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MHTML) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MHTML extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MHTML file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MHTML extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MHTML extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MHTML file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MHTML file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MHTML file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MHTML file) will be extended to the maximum.
It is also good to check
- if the .MHTML file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
