Disclosed herein is an inner sleeve for files. The inner sleeve for a file comprises an elongated binding portion (10) vertically extending at one side thereof, and a paper receiving portion (20) having a rectangular envelope shape defined at a remaining portion thereof. The binding portion is punched with a plurality of binding holes for allowing the inner sleeve to be bound to the file using a binder or spring. The paper receiving portion is open at an upper end thereof to form a paper insertion opening. The inner sleeve is made of transparent materials. A plurality of fitting slits (22', 23', 24', 25') having a certain length are formed at both front and rear surfaces of the paper receiving portion so as to allow four corners of respective papers, to be kept individually, to be fitted thereinto, thereby securing stable storage of the fitted papers. |
