What is a DO file?
Files with the .DO extension are executable Java browser programs launched using a server that supports the technology – i.e. servlets. Files with the .VCS extension can be identical to .DO files for the purposes of specialized task scheduling programs – this is typically seen in files generated by webinar software.
DO files are also schemes for mapping URL addresses in a browser app, used by Java Struct controllers. DO files are used for generating dynamic websites.

More information about DO file
DO is a Java Servlet file representing a web-based Java application run on server supporting Java programming language, e.g. IBM WebSphere. DO files store Java application pages to be run on WWW server.
Java Struts files
DO files are also known as Java Struts application files. DO file contains related URL address that allows creation of function mapped to to given Struts controller which processes DO files.
DO file applications
DO file’s main goal is generating dynamic web pages. DO files are placed on the server along with other resources required by the website. Such solution allows website to download necessary information from the server and render page in the web browser based of the code in DO files. Usually such websites use HTML, although XML format can also be used. Java Servlet files are commonly considered as valid CGI, ASP.NET, or PHP counterparts.
How to open DO files
If you cannot open the DO 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 DO 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 DO file can be found in the table. Now just download and install the appropriate application.
Possible problems with the DO format files
The inability to open and operate the DO 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 Java Servlet Format file. Below is a list of possible problems.
- Corruption of a DO file which is being opened
- Incorrect links to the DO file in registry entries.
- Accidental deletion of the description of the DO from the Windows registry
- Incomplete installation of an application that supports the DO format
- The DO 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 DO file.
- Drivers of equipment used by the computer to open a DO 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 DO file should operate with your programs without any problem. If the problem with the DO file has not been solved, it may be due to the fact that in this case there is also another rare problem with the DO 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.DO) you have two ways to do it. The first and the easiest one is to right-click on the selected DO 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 DO 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. DO) 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.
