Did you find an XXXXXX file on your computer and wonder what program should open it? Maybe someone emailed you an XXXXXX file but you're not sure how to use it. Perhaps you tried to open the XXXXXX file but Windows told you that it could not open it.
Before you can open an XXXXXX file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .XXXXXX file extension refers to.
Other types of files may also use the XXXXXX file extension. If you know of any additional file formats that use the .XXXXXX extension, please let me know so I can update this information.
How To Open an XXXXXX File:
The easiest way to open an XXXXXX file is to double-click on it and let your PC decide which default application should open the file. If no program opens the XXXXXX file then you probably don't have an application installed that can view and/or edit XXXXXX files.
Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.
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% of a song if 50% 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.
On the other hand, if a file is completely downloaded but is still in the whatever.XXXXXX form, you could try renaming the file to whatever.mp3, for example, and seeing if that works. It's possible allTunes had some kind of 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.

Tip: Use Notepad or another text editor to open the XXXXXX file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This probably isn't the case with XXXXXX files but it might be worth a try if you suspect the file is text based.
If you find that an application on your PC does try to open the XXXXXX file but it's the wrong application or if you would rather have another installed program open XXXXXX files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.
How To Convert an XXXXXX File:
There are two main ways to attempt to convert an XXXXXX file to another file type:
- Open the XXXXXX file in its default program and choose to save the open file as another file format.
- Use a File Conversion Online Service or Software Program to convert the XXXXXX file to another file format.
The first option involving opening the XXXXXX file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens XXXXXX files, a third-party file conversion tool (the second option) could be very useful. Neither of these methods are going to work if the XXXXXX file truly is an allTunes partial download file.
Important: You cannot usually change a file extension (like the XXXXXX file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
