DestinationDirs

DestinationDirs is a directive used in Windows resource script files (.rc) within the Windows development toolchain. It instructs the resource compiler (such as rc.exe) on how to assign resources to destination locations when building a resource package or embedding resources into an executable or library. The directive enables a project to organize resources—such as icons, bitmaps, dialogs, or version information—by mapping resource identifiers or types to logical destination categories or directories used by the build or packaging process.

Usage context and behavior can vary by toolchain and project, but the general purpose is to influence how resources are organized within the compiled resource data. DestinationDirs is typically encountered in more complex or legacy RC workflows where resources need explicit grouping or naming conventions that align with a particular packaging or deployment strategy. Because it is tied to older RC syntax, modern Windows development often relies on alternative mechanisms—such as manifest-based deployment, MSI/WiX packaging, or standard resource layout—than on DestinationDirs.

Notes and caveats: DestinationDirs is considered a niche feature within the Windows resource editing ecosystem. Its exact syntax and impact depend on the toolchain and version being used, and in many contemporary projects it is not required. Developers who encounter DestinationDirs should consult the specific compiler documentation and any project-specific build scripts to understand how it affects resource packaging and installation.
