.DO File Extension
What is a DO file?
A DO file is a web-based Java program run by a web server that supports Java, such as Tomcat or IBM WebSphere. It is typically mapped to the Struts controller, which processes the file. DO files are used for generating dynamic webpages.
Some webinar programs may generate DO files that are formatted as .VCS files. Changing the file extension to ".vcs" may allow these files to be imported into various scheduling programs.
NOTE: The ".do" extension may also be a URL mapping scheme for a web application and not a file extension. For example, the Struts framework often uses the ".do" string for mapping Java servlet actions in the web.xml configuration file.

What is a DO file?
A DO file is a disk image created for use with an Apple II computer. It contains data that was imaged from an Apple II's hard disk, for use as a backup or historical archive. DO files are saved using DOS 3.3 sector order, as opposed to ProDOS sector order.
Various tools allow Apple II series users to save the contents of their computers' hard disks as disk images. These images can include applications, files, and other data stored on the computers.
Users can save Apple II disk images in many different formats. Most commonly, Apple II disk images are saved as .DSK files. However, the images may also be saved as DO files or .PO files. DO files store data in DOS 3.3 sector order; PO files store data in ProDOS sector order. (Some Apple II computers used the DOS 3.3 operating systems, while others used ProDOS.)
How to open a DO file
You can open a DO file in several Apple II disk image utilities and Apple II emulators. For example:
- CiderPress (Windows) allows you to open a DO file to examine, extract, or add to its contents
- Apple Disk Transfer ProDOS (multiplatform) allows you to transfer DO files to an Apple II computer.
- KEGS (Kent's Emulated GS) (multiplatform) allows you to open and mount DO files.
How to convert a DO file
CiderPress can convert DO disk images to other disk image formats, including:
