The HMT (HighMAT File) file extension is a multimedia container format developed by Microsoft Corporation in 2002. It is primarily used to store digital media content such as audio, video and images in optical storage media, such as DVD and CD-ROM discs. The primary purpose of HMT files is to provide a higher compatibility between Windows Media Player versions and the optical media which makes the media easier to access from different devices. The main features of HMT files that make them distinct from other multimedia container formats are its primarily stored data streams in a multiplexed form, allows the soundtracks to be encoded as either an original multi-channel DirectSound format or as Dolby Digital stream, supports series of multiple digital video format and lastly, stores the information with an Unicode character set.
Similar File Formats
Similar file formats associated with the HMT file extension includes .BIN, .WPL, .BMF, .WMV, .ASF and many other related multimedia container formats.
Compatibility
HighMAT files can be opened by various Microsoft Windows programs, including Windows Media Player 10, Windows Media Center 5, Windows XP Media Center Edition 2002 Service Pack 1 (SP1), Windows Vista 2, Windows XP Professional 3 or later versions, along with other third-party media players such as VLC media player. Additionally, these files can also be opened with some non-Microsoft Windows software like Roxio's Easy CD Creator 5.0/DirectCD 5.0or RealNetworks' RealPlayer 10.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .HMT) 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 .HMT 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 .HMT 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 .HMT 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 .HMT extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .HMT file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .HMT 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 .HMT file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .HMT file) will be extended to the maximum.
It is also good to check
- if the .HMT file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
