Bookmark Format | CyberLink | Video Files |
The BMK (PowerDVD MovieMark File) file extension is a special type of movie bookmark created by CyberLink PowerDVD. Users create their own bookmarks while watching Blu-ray, HD DVD, and other disc formats in order to quickly access their favorite scenes. The single file contains user metadata such as name, location, and timestamp information. The BMK file is one of several bookmark files that are generated by PowerDVD’s ‘MovieMark’ feature that allows users to mark scenes they want to watch again or share with others.
Technical Details
BMK files are stored in a proprietary binary format and often have either a.bmk or.mkb file extension. These files are used to store key scene information inside the program. The actual video content is not embedded within the file itself. Instead, it creates a link back to the original DVD or Blu-Ray source file. BMK files can only be opened within CyberLink PowerDVD. Other similar file extensions include bkm, dvbookmark,and .kmz.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BMK) 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 .BMK 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 .BMK 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 .BMK 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 .BMK extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BMK file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BMK 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 .BMK file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BMK file) will be extended to the maximum.
It is also good to check
- if the .BMK file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
