ABSTRACT:
A file managing apparatus is disclosed which is capable of restoring deleted files with ease. When a user gives an instruction to delete a file6, a parent entry number for the file6is changed from “1” to “2” in a property list having the entry number6associated with the file6. Because the parent entry number that is set for the value “2” points to the entry of a recycle bin, the file6is placed in a virtually deleted state. Any virtually deleted file is later restored easily through simple processing.
