Format conversion apparatus and file search apparatus capable of searching for a file as based on an attribute provided prior to conversion

摘要

A portion identifying a file attribute identifies an attribute of an unconverted file (e.g., a name of an application used to create a document). A file format converter converts the file in a selected format. A portion adding a file attribute and writing it to a file provides the identified file attribute in the form of text and adds it to the file. After a file is converted in format, an original file attribute can still be referred to. A file attribute, such as an application used to create a document, can be used to sort and search for a file.
