What is a HTML file?

File with a .HTML contains source code of a web site written with the Hypertext Markup Language – text, references to graphics, charts and formatted elements, displayed by a web browser on a static web site. The code is written in text format with tags which dictate the structure and formatting of a web site.

HTML web sites can be opened within the notepad, however, for this purpose usually dedicated software is used. Such software can make the work easier, they give hints and highlight fragments of syntax and they contain templates. The index.html files are utilised as the start pages for the web browsers demanding access to catalogues of a given web site. In case of Windows WWW servers, these are the default.html files. HTML code is analysed by a web browser and displayed in a proper form to a viewer, and if a viewer wants to see its text form, specific option has to be chosen in the browser.

How to open HTML files

If you cannot open the HTML file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports HTML among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the HTML file can be found in the table. Now just download and install the appropriate application.

Possible problems with the HTML format files

The inability to open and operate the HTML file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the HTML Hypertext Markup Language Web Page Format file. Below is a list of possible problems.

  • Corruption of a HTML file which is being opened
  • Incorrect links to the HTML file in registry entries.
  • Accidental deletion of the description of the HTML from the Windows registry
  • Incomplete installation of an application that supports the HTML format
  • The HTML file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the HTML file.
  • Drivers of equipment used by the computer to open a HTML file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the HTML file should operate with your programs without any problem. If the problem with the HTML file has not been solved, it may be due to the fact that in this case there is also another rare problem with the HTML file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.HTML) you have two ways to do it. The first and the easiest one is to right-click on the selected HTML file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the HTML file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. HTML) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
