PHT File Summary

There is one file type associated with the PHT File Extension, the Partial Hypertext format. According to our database, three distinct software programs (conventionally, Internet Explorer developed by Microsoft Corporation) will enable you to view these files. PHT files are categorized ordinarily as Web Files.

Both desktop and mobile devices enable you to view and (sometimes) edit these files, depending on the software used. PHT files have a "Low" Popularity Rating; this means that they are not present on most devices.

Although there is a lot more to know about PHT files, those are the most important details of these types of files. If you are having trouble opening these files, or would like more detailed information, please see our comprehensive information below.

PHT File Complications


Issues Opening PHT Files

Missing Internet Explorer

You attempt to load your PHT file and get an error such as "%%os%% Can't Open The PHT File Extension". When this happens, it is commonly due to Internet Explorer missing in %%os%%. The OS won't know what to do with your PHT file, so double-clicking to load the file doesn't work.


Tip: If you have another software that you know opens PHT files, you can select it by hitting the "Show Apps" button.


Incorrect Internet Explorer Version

Occasionally, you might have an outdated version of Internet Explorer installed that's incompatible with your Partial Hypertext type. Installing the latest version of Internet Explorer from Microsoft Corporation is recommended. Most of the time your Partial Hypertext file was created by a newer Internet Explorer than what you have installed.


Tip: Investigate your PHT file by right-clicking and selecting "Properties" to find clues on what version you need.


Conclusion: The majority of PHT file opening issues are due to not having the correct Internet Explorer version installed.


Other Causes of PHT File Opening Problems

Errors opening Partial Hypertext files can still occur even with the latest Internet Explorer software installed on your computer. There can be external issues inside of %%os%% that are causing these errors when opening PHTs. Additional factors include:

  • Invalid PHT file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Unintentional removal of the description of the PHT file inside the Windows Registry
  • Internet Explorer or another PHT application experienced a flawed installation
  • Something has caused file corruption of your PHT
  • Past or present virus infection has affected your PHT
  • Device drivers of the hardware associated with your PHT file are corrupt or out-of-date
  • Windows cannot load your Partial Hypertext file due to insufficient resources (eg. RAM)
