A DTD ( .dtd) file extension is a type of markup language used to indicate structural aspect of a document. It is usually found in text-based documents such as the Extensible Markup Language (XML), HyperText Markup Language (HTML), or SGML (Standard Generalized Markup Language) documents. It is an instruction manual that specifies document properties and how they should be expressed. This include the tags and attributes that can be used when writing documents, how they are used and what they may contain.
How does it work?
The DTD file ( .dtd) describes how text should appear when published, formatted for print, and converted into HTML. It separates document data from presentation data. It describes which elements are used in a document, as well as which attributes can be applied to them, such as size, color, font-family etc. Furthermore, the DTD defines a specific hierarchy and indicates what elements can be used inside other elements. Additionally, these files provide rules on how many instances of any element can appear in any given location.
Other similar file extensions
Similar file extensions include .xsd, .dcl, .xml, .rss, .html, .htm, and .sgml.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DTD) 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 .DTD 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 .DTD 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 .DTD 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 .DTD extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DTD file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DTD 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 .DTD file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DTD file) will be extended to the maximum.
It is also good to check
- if the .DTD file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
