A file data retrieving system includes a filing device for storing file data and retrieval-use-image data used for retrieving file data. The file data is stored in a predetermined data form. The retrieval-use-image data has an image density smaller than that of the file data. The system also has an image data reproducing circuit for reproducing image data to be displayed from each of the file data and the retrieval-use-image data. Further the system has a display unit for displaying the image data supplied from the image data reproducing circuit. The display unit displays the image data reproduced from the retrieval-use-image data at the time of retrieval of the file data.
