Abstract
A method, system, and computer usable program product for preserving references to deleted directory entries are provided in the illustrative embodiments. An instruction to delete an entry is received. A second entry referencing the entry is identified. The second entry is marked as a ghost reference to the entry. The entry is converted to a deleted entry. A ghost attribute with a value of 'false' may be added to the entry. A ghost attribute or tag with a value of 'false' may be added to the second entry. The ghost tag may correspond to an attribute of the second entry that references the entry. An entry may be deleted by setting a value of a ghost attribute in the entry to true. The second entry may be marked as the ghost reference by setting a value of a ghost attribute or a ghost tag in the second entry to true.
