Opening DO files
Did your computer fail to open a DO file? We explain what DO files are and recommend software that we know can open or convert your DO files.
What is a DO file?
The files that contain the .do file extension are normally used to generate dynamic Web pages for websites on the Internet. The DO files contain Java program pages that have been created with the purpose of being run by a web server, with the information then being transferred back to the user's Web browser.
Files with the .do file extension work much in the same way that a PHP file works. The DO files are also known as Java Struts Application Files because the DO file provides an associated URL with the ability to "map" to specified Struts actions.
Software that will open, convert or fix DO files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
