By this property if you want to check file has been removed ,deleted from physical path then this will be true and you can check like if you have a tree view and you dont want to repopulate your tree view then use filesystemwatcher and repopulate the tree only when files have been changed,delete or rename. or you can throw a messagebox like above.
