How to open file with .XPT extension?

Don’t you know what program to use to convert the .XPT file? Do you want to convert a .XPT file into a different format? Below you will find helpful information.

File extension .XPT

Full Name Developer Category
Mozilla Firefox Component N/A Plugin Files
.XPT

XPT is a file format used by the Mozilla Firefox web browser. It is an XML-encoded list of various components and is primarily used to store lists of prefs that are localized for the internationalization of Firefox. These prefs can be localized without changing the Firefox UI source code. The XPT files are also used to store interface information that allow different add-ons and applications to interact with Firefox more easily. The XPT payloads are stored in the global databases which can then be accessed by the Mozilla platform for loading the correct resources when necessary.

Technical Information

The XPT file extension is associated with the XML format, and follows straightforward rules for its structure. An XPT file contains a map of all the JavaScript functions in a module, including their parameter layout and return values. It's located in a specific directory inside a Firefox package, usually named "components". Since the XPT format is derived from XML, some software applications may be able to parse and generate XPT files. Other common similar file extensions used by Firefox include: XUL, DLL, XPCOM, and JSON.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .XPT) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .XPT extension.

When choosing the software we can select the system to use this software every time.

Remember!
Using it for the first time it is good to check whether the .XPT file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .XPT extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .XPT extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .XPT file. Sometimes you have to repeat the operation several times.

Other instructions

If none of the programs listed by us to work with the .XPT file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.

In the vast majority of cases you will find the program dedicated to support the .XPT file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .XPT file) will be extended to the maximum.

It is also good to check

  • if the .XPT file has no errors
  • or if it has been copied (or downloaded by the browser) thoroughly
In such a case it is best to try to download the .XPT file again from the same source on the Internet (or look for another source). If you received the file from another person, ask this person to re-send it. However, if the file was copied from some media, repeat the copying operation.
