File Types Design Cryptocurrency MS Office Windows Linux Google Drive Apps File Types Backup & Utilities View More Tweet Share Email A file with the XXXXXX file extension (that's the letter X six times) is most likely an allTunes Partial Download file created with allTunes, a program that lets you search for and purchase music from your computer. The MediaMonkey music manager may also assign the XXXXXX file extension to files, temporarily, while it builds ID3 tags, creating something like whatever.MP3.XXXXXX. XXXXXX files are similar to other partial or incomplete file formats like BC! files used with BitComet or BitLord, and the Chrome web browser's CRDOWNLOAD files. However, even though they're used for the same purpose, none of these files are interchangeable (i.e., you can't use a BC! file in place of an XXXXXX file). How to Open an XXXXXX File XXXXXX files are the partially complete downloads from the allTunes music download program. In most cases, an XXXXXX file isn't usable because the file isn't complete. A music or video file can't be played if all the data isn't there. For example, you can't usually play the first 50 percent of a song if only half of the file is downloaded. Your best bet is to simply wait until the file is completely downloaded, at which point allTunes will rename the file as you'd expect to find it. Another option is to open the incomplete file in VLC since it's capable of playing music files as they're downloading, but this is only useful in some situations where you want to get a head start on listening to the file before it's fully available. On the other hand, if a file is completely downloaded but is still in whatever.XXXXXX form, you could try renaming the file to whatever.mp3, for example, and see if that works. allTunes might have experienced an error that prevented that last renaming step. Finally, if you're sure the XXXXXX file in question is not complete but also isn't progressing as expected, you should stop the download in allTunes and restart it. That should take care of the problem. MediaMonkey uses the XXXXXX file extension also, and just like with allTunes, the program should automatically remove the file extension when it's done using it. If it doesn't, you should try to exit and then reopen the program. GOM Player might use this file extension, too. A different program might also be currently using the file, locking it in place and not allowing MediaMonkey to rename it. In this case, you can either try to shut down all the programs you think might be using the file or restart your computer to release it. You might then have to manually rename the XXXXXX file to whatever file extension the file should have. While it's probably unlikely, you could find that more than the program you already have installed opens XXXXXX files natively. If that's the case on your computer, and the one that's currently configured as the default program for this extension is not the one you'd like to open them, see how to Change File Associations in Windows for instructions on how to fix this. How to Convert an XXXXXX File Since XXXXXX files are not full files, you can't convert one into a new format. However, as we mentioned earlier, renaming the file — if you happen to get that to work — can let you use a free file converter to convert that regular, functioning file to any other format that the converter supports. For example, if you're able to rename an XXXXXX file to an MP3 file, and find that it works like an MP3 file, you can then use a free audio converter to convert that MP3 file to WAV or some other sound file. Still Can't Open Your File? An XXXXXX file isn't the same as an XXN or an XXX file, which is either a generic file that a program appended the Xs to or a Compucon Singer Embroidery file that's used with Compucon USA's EOS software. XXEncoded files (XX or XE files) are different, too, used instead with programs like PowerArchiver. XXD is another similarly named file extension that's for Brixx Planner Calendar files used with Brixx. As you can see, some file extensions look very similar to XXXXXX files, but that doesn't mean they're related at all or that you can open them with the same software programs. Be sure to really look at the file extension to confirm that you're dealing with XXXXXX files. Some might even have one less or one more X and could be used with an entirely different program.
