You're here because you have a file that has a file extension ending in .pvm. Files with the file extension .pvm can only be launched by certain applications. It's possible that .pvm files are data files rather than documents or media, which means they're not meant to be viewed at all.

Files in the PVM format can be opened and viewed using a Javascript Web media player integrated into HTML pages of websites and Web applications. Some PVM files can also be viewed using Web browsers integrated with playback support for standard specifications implemented by the Optical Storage Technology Association (OSTA) for such PVM files. Developed by OSTA using the standard MPV format, PVM files generally contain audio, video and other digital media content, much like MPV files. The MPV format is default standard technology comprised of a series of specifications based on the XML format. The MPV format was developed for seamlessly facilitating data processing and playback of digital images, videos and audio content using computers and a wide variety of devices that can be used to view content stored in DVDs, CDs and internal or external data storage gadgets like hard disks and memory cards. MPV technology was developed by various supporters of OSTA's objectives, and with the creation of PVM file format technology, the efficiency of MPV standards was improved in terms of viewing digital audio, video and images stored in resources on the Internet with the use of compatible Web browsers. The set of specifications based on XML technology contained in PVM files can be interpreted by a compatible Javascript audio and video player found in an HTML page. The HTML page with the Javascript player and the PVM content are all stored in the PVM file.

Launch a .pvm file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .pvm file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .pvm files aren't yet associated with it. In this case, when you try to open a .pvm file, you can tell Windows which application is the correct one for that file. From then on, opening a  .pvm file will open the correct application.

Be careful not to rename the extension on .pvm files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .pvm. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
