Borland Project Desktop File

A DSK file may also be a project used by Borland Delphi and Borland C++ Builder development environments. It stores information about a development project, including open editor windows, workspace settings, and references to files (it does not contain actual source code or compiled programs). DSK files function as workspace configurations for organizing development environments, allowing developers to resume work with the same layout and files as in their previous session.

More Information

Borland Delphi and Borland C++ Builder primarily used DSK files during the 1990s and early 2000s. As development tools evolved, Borland’s Delphi and C++ Builder software transitioned to newer product versions, particularly with Delphi 2005 and beyond.

These newer versions and other modern Integrated Development Environments ( IDEs ) began using different formats for project management. For example, Delphi 2005 and later versions adopted the .DPROJ format for project files, leading the software to phase out DSK files.

A DSK file may also be a database created by DSKE Simple IDs, a now-discontinued program for making identification cards. It contains information related to ID cards, such as names, photos, contact information, and other personal details that Simple IDs uses to generate unique identification cards.

More Information

Simple IDs is a software program for generating ID cards for employees, members, or events. Individuals or organizations can personalize ID cards with the software by inputting information such as names, photos, and contact details. This information is saved in the DSK database format, which you can view and edit with the software.

While it was once more commonly used for basic ID card creation, DSKE discontinued Simple IDs as more feature-rich ID card management software, such as cardPresso and AlphaCard, gained popularity.
