What is a DSC file?
A DSC file, identified by the .dsc extension, is a legacy text description file historically used to detail software information. Saved in a universal plain text format, these files can be effortlessly opened and viewed in any popular text editor, from Microsoft Notepad and Notepad++ to Apple TextEdit. Their contents typically included vital pre-installation details such as the product description, specific data parameters, minimum system requirements, and setup instructions. Over time, the standalone DSC file format has become largely obsolete. Its functional role has been superseded by the more integrated and common “readme” files that are now standardly bundled with applications to guide users through the software’s pre-launch setup process.
