These MOGG files contain OGG audio files that are stored in such a way that each OGG file can play separately or together with all the others. The MOGG file stores each OGG file in a separate track so that they're not bound to the same playback stream. Some MOGG files may instead be MedCalc Data files but most will be music files. How to Open a MOGG File You can play MOGG files on a computer for free using Audacity. MOGG files are also supported in Avid Pro Tools software, Steinberg Nuendo, and REAPER. If you open the MOGG file in Audacity, you'll have the option to save the audio data to a new format. See the section below on converting for more information. OGG files are much more usable than MOGG files. See the several applications that let you play OGG files here: What Is an OGG File? MOGG files that are used with the statistical program MedCalc probably can't actually be opened manually by the software, but are instead just regular data files that the program needs to function. In other words, the MOGG files are likely stored in the program's installation folder so that MedCalc can use them as needed, but there probably isn't a menu within the program that will let you import the file. Though it doesn't apply to audio files like Multitrack Ogg files, some MOGG files might just be text files that have the .MOGG extension. If so, you can use any text editor, like Windows Notepad or another free text editor, to open the MOGG file. Depending on the specific program that created your file, you may be able to see some or all of the data that makes up the MOGG file, which might help you determine the program that should be used to open it. How to Convert a MOGG File A Multitrack Ogg file can be converted to another audio format using Audacity. The program supports exporting the MOGG file to WAV, OGG, MP3, FLAC, WMA, as well as some other common audio formats. With Audacity, you can choose to export the entire MOGG file or even just a single stream. To convert just one section of the MOGG file, first select the audio you want to be converted and then use Audacity's File > Export Selected Audio... menu option to choose an output format. OggSplit+ is a portable and free tool that should be able to split a MOGG file into the different OGG files that it's made up of. You'll need a file extractor program like the free 7-Zip to extract the OggSplit+ program from the archive, after which you can drag the MOGG file onto the OggSplit+.exe file to use it. We can't think of a good reason you'd ever want to convert a MOGG file that's a MedCalc Data file to another file format. Considering the role it plays in that program, any conversion done on it would probably render the file useless. Still Can't Open Your File? If none of these programs can open your file, make sure you're reading the file extension correctly. It's possible that you're just misreading the suffix and thinking that your file belongs to the same format as MOGG files when really it's entirely different. For example, some files, like MGO (MacGourmet Recipe) files, share some of the same file extension letters but have nothing to do with any MOGG file format. Similar is the MOGRT file extension that's used for Adobe Motion Graphics Template files. While the file extension might closely resemble MOGG, the format is actually only usable with Adobe Premiere Pro. MagGourmet Recipe files is one last example. They use the MGO file extension and are used with the MacGourmet Deluxe program. If it's not already clear, the idea here is to identify the file extension and then research the one your file is using. That's the easiest way to learn what format the file is in and ultimately, the program that can be used to open or convert the file.
