How to open files with .tag extension

The .tag filetype is fairly obscure. You won’t run into it much unless you’re a programmer or web design enthusiast. However, if you are not, you may find yourself concerned that these files are part of an elaborate viral infection if they’re on your PC.

The following guide should help you dissolve those worries. You will learn what files with the .tag extension do and how to open them.

What are .tag files?

It’s interesting at just how many use-cases there are for TAG files. For instance, in web design and development, TAG files are used to build custom tags. They are usually written as mini JSPs (JavaServer Pages).

TAG files typically have one function. Once a programmer defines them, a plethora of JSPs, programs, and/or web pages can use and re-use them.

WordSmith Tools, a software suite used for word analysis in texts and applications, uses TAG files to extend and add custom functionality. Some programs use them for simple metadata. If you’re unfamiliar with what metadata is, it’s essentially more descriptive information about data or a file.

Other programming tools that create and utilize .tag files include DataFlex and COREX. Both of these are visual object-oriented programming tools for developing multiplatform software applications. These tools for data mapping purposes use TAG files.

1. Using HTML CoffeeCup HTML Editor

  1. Download and install CoffeeCup HTML Editor.  You don’t have to run CoffeeCup HTML Editor after the setup is complete.
  2. CoffeeCup HTML Editor will assign itself as the default program to run any web-design related files (that don’t already have default programs to run them). All you have to do is open Windows File Explorer, navigate to where the .tag file is and double-click on it.Use file explorer to open TAG file.
