File extension .DTD

File description

The DTD file format stands for Document Type Definition. All such files that comprise of the DTD extension are the text files that indicate certain elements that are XML, XHTML, HTML or the SGML document.

The information that these DTD files hold are useful in defining the structure of the mentioned XML data. Such data may be defining the nesting and order of a document’s attributes and elements, which are referenced within a web page. The DTD files enable a system that is receiving the XML from other system to agree on the particular structure of the XML information that is being transmitted, validating uniformity.

Description of the problem

If you have on your computer a .DTD file that you cannot open, you are in exactly the same situation as thousands of other people who have similar problems with this or any other unknown file.

There may be several reasons why you cannot open the file with .DTD extension. Directly on this website you can find a solution of the most common problem with the .DTD file – that you do not have on your computer the appropriate program to open the file.

Solution

From the list below, select the appropriate program, install it and double click on the icon of a file that did not want to open - the problem with the .DTD file extension should be solved. However, if this does not happen, go back to the website to learn about other possible causes of the error, which have been described at the bottom of the website.

Other possible reasons why your .DTD file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .DTD file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DTD file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DTD file, so download the update and check again.

2. Incorrect .DTD file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .DTD file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
