What are HLP files and how to open them

Are you having problems opening a HLP file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a HLP file?

HLP files have multiple uses, and Windows Help is one of them. Read more about the other uses further down the page.

Windows Help File

The HLP file format is an outdated file format that was used by Microsoft Windows to contain help files. It was designed to give users context-specific guidance within their software. This format is based on Rich Text Format (RTF) and usually holds text, images, and formatting data.

An advantage of the HLP file format is its capacity to incorporate hyperlinks and cross-references, allowing users to easily move between sections of the help material. Moreover, .HLP files can be searched with the inbuilt search feature of the Windows help viewer.

Unfortunately, .HLP file format has become almost obsolete in recent times because of the lack of support on modern OSs. In prior versions of Windows, .HLP files could be viewed through WinHlp32.exe, but this utility is not included by default in Windows 8 or later.

How to open HLP files

Important: Different programs may use files with the HLP file extension for different purposes, so unless you are sure which format your HLP file is, you may need to try a few different programs.
