Patent ID: 8306957

Claim:
An information managing apparatus in a multi-layer file system comprising: at least one computer processor configured to execute a plurality of units comprising: an acquiring unit that acquires information stored in a storage unit; a condition setting unit that sets a plurality of conditions on at least one layer and an attribute value of at least one subordinate layer provided subordinate to the at least one layer of the file system which manages the information stored in the storage unit, wherein: at least one subset of the stored information must satisfy at least one of the set conditions in order to be correlated with the at least one layer as information located subordinate to the at least one layer, and the at least one subset of the stored information must satisfy the set attribute value in order to be correlated with the at least one subordinate layer; a condition judging unit that judges whether or not the acquired information satisfies at least two of the set conditions; and a correlating unit that correlates the acquired information with the at least one subordinate layer only when: the condition judging unit judges that the acquired information satisfies the at least two of the set conditions; and the acquired information satisfies the set attribute value of the at least one subordinate layer, wherein: the condition setting unit generates a condition formula describing each respective folder that is subordinate to at least one condition-associated folder provided on the at least one layer, the at least one condition-associated folder is a folder for which at least a condition must be satisfied by information to be correlated with the folder as information located under the folder, and the condition formula is based on elements comprising: a respective one of the plurality of conditions that is set for the at least one condition-associated folder; and an attribute value of the respective folder that is subordinate to the at least one condition-associated folder, wherein: the at least one layer comprises a first condition-associated folder f A and a second condition-associated folder f B , a subordinate folder SF A2 is provided subordinate to the first condition-associated folder f A , the subordinate folder SF A2 is also provided subordinate to the second condition-associated folder f B , the condition setting unit generates a condition formula for the subordinate folder SF A2 comprising f A (α, β A2 ) OR f B (α, β A2 ), α is an attribute value corresponding to a respective monitoring subject folder, and β is an attribute value corresponding to a respective subordinate folder.
