Abstract: The present invention is to improve user operability when the same operation is repeated on a document image management device. A device having a executing unit for receiving selection of processing to be executed on a file or folder from an operator, and executing the processing, which selection is received, on the file or folder, includes: a search unit for searching for a file or folder on which the processing has been executed in the past in the executing unit when receiving the selection of the processing from the operator; and an operation target display unit for showing on a display screen the identification information on the file or folder searched for by the search unit.

Abstract: An encrypted document file and related file are received (S42), and character strings are extracted from the related file. The document file is registered in a database (150) together with the extracted character strings (S45).

Abstract: In a case that documents satisfying search conditions input on a retrieval device are retrieved and there is a plurality of retrieved documents, the priority levels of the retrieved documents are determined based on the installation site of the retrieval device, information on the date and time when a search is executed, and information on the schedule of events at the installation site, with the display order of the plurality of retrieved documents determined, and the documents displayed, based on the determined priority levels.
