摘要：
A file managing apparatus is disclosed which is capable of restoring deleted files with ease. When a user gives an instruction to delete a file 6, a parent entry number for the file 6 is changed from “1” to “2” in a property list having the entry number 6 associated with the file 6. Because the parent entry number that is set for the value “2” points to the entry of a recycle bin, the file 6 is placed in a virtually deleted state. Any virtually deleted file is later restored easily through simple processing.
