A best practice is to always use the environment variables `%SystemDrive%` and `%ResourceDrive%` instead of hard-coded file paths. The root path returned from these two environment variables has shifted over time from `d:\` to `c:\`. However, older applications hard-coded with file path references to `d:\` will continue to work because the App Service platform automatically remaps `d:\` to instead point at `c:\`. As noted above, it is highly recommended to always use the environment variables when building file paths and avoid confusion over platform changes to the default root file path.
