What is an X_T File?

Question: What is an X_T File?

Did you find an X_T file on your computer and wonder what program should open it? Maybe someone emailed you an X_T file but you're not sure how to use it. Perhaps you tried to open the X_T file but Windows told you that it could not open it.

Before you can open an X_T 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 .X_T file extension refers to.

Answer: A file with the X_T file extension is a Parasolid CAD file.

Other types of files may also use the X_T file extension. If you know of any additional file formats that use the .X_T extension, please let me know so I can update this information.

How To Open an X_T File:

The easiest way to open an X_T file is to double-click on it and let your PC decide which default application should open the file. If no program opens the X_T file then you probably don't have an application installed that can view and/or edit X_T 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.

X_T files are CAD part files that can be opened with Autodesk Fusion 360, VectorWorks, or Siemens PLM Software called Parasolid.

If you know anything else useful about X_T files, please let me know so I can update this page.

Tip: Use Notepad or another text editor to open the X_T 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 may or may not be the case with X_T files but it's worth a try.

If you find that an application on your PC does try to open the X_T file but it's the wrong application or if you would rather have another installed program open X_T 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 X_T File:

There are two main ways to attempt to convert an X_T file to another file type:

The first option involving opening the X_T 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 X_T files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the X_T 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.
