Windows Media Video is what the .WMA extension stands for. The file format is useful in compressing the video based format that was developed by the Microsoft Corporation for streaming applications online. Most of the movies and videos that are available online are in the .WMA file format.
Files with the extension .MPJ contain an HTML documentation project created in older versions of Adobe RoboHelp. In the software, help files of any type can be saved with the extension .HHP.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the WMV file after converting to MPJ may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from WMV to MPJ to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting WMV to MPJ does not meet your expectations, you can simply try to find on the Internet a different version of your file in WMV format, properly converted to a MPJ file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file WMV the desired result was not achieved, you can try to change the format of WMV file to other than MPJ. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your WMV file converted by someone else, and the attempt to convert it to MPJ on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the WMV file in its original format (without conversion to MPJ file). Such a solution will be difficult to implement, but it certainly will give the best result.
