To solve such a problem that a document file formed by fastening a document holding plate comprising a base section which is bonded to a support plate, and a holding section for pinching documents with the support plate to the support plate has a function for pinching documents, but does not have the function which enables the movement of a tag for marking to the next document of an already read document every time a page is turned.
The function which enables the movement of the tag for marking to the next page of an already read page every time a page is turned when documents are bound by a filing tool is realized by providing a tongue section having a tag function on the side edge section of the filing tool formed of the support plate made of a bond paper or a synthetic resin sheet or the like.
