Removes a single WIM data source from backing files on a volume.
HRESULT WofWimRemoveEntry( PCWSTR VolumeName, LARGE_INTEGER DataSourceId );
The volume name which contained files whose data was provided by the WIM.
Identifes the WIM entry.
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
If the volume currently has files whose data is derived from the WIM file, the data for those files will become permanently inaccessible. It is good practice to remove any files referring to the WIM file prior to removing the data source from a volume. Once all data sources for a WIM file have been removed, the WIM file itself can be renamed or deleted.
