.DO File Extension

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.

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.

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.

CiderPress can convert DO disk images to other disk image formats, including:

• .PO - ProDOS Order Apple II Disk Image
• .2MG - Apple IIGS Disk Image
• NIB - Unadorned Nibble
• SDK - ShrinkIt Disk Archive
• APP - TrackStar Disk Image
• HDV - Sim //e Virtual Hard Drive
• DDD - DDD Pro Image
