You may be unable to delete the cache of offline files from the client-side caching (CSC) cache on an offline Windows Vista-based client computer

On an offline Windows Vista-based client computer, you may be unable to delete the cache of offline files from the client-side caching (CSC) cache.

Note This issue occurs when the offline files are ghost items. Ghosting is a new feature for offline files in Windows Vista. When only partial file contents are cached, or when partial directory contents are cached, CSC creates ghost items. Ghost items cannot be deleted. Additionally, the ghosting feature cannot be disabled in Windows Vista.
