     FIELD OF THE INVENTION 
     The invention relates to suspension file folders with index tab holders and index tabs for use on file folders and data separation sheet members. The index tab holders can be positioned in selected locations on top sections of the file folders. 
     BACKGROUND OF THE INVENTION 
     Hanging file folders have support bars with downwardly open hooks on opposite ends to support the folders on horizontal rails of a file drawer. Folded paper sheet members have top sections turned over the bars to retain the bars on the sheet members. The top sections are provided with laterally spaced slots to accommodate index tab holders in selected positions along the top sections of the file folders. The index tab holders have end fingers that must be inserted into the slots in the file folders to mount the index tab holders on the file folders. The number and location of the slots limit the locations of the index tab holders relative to the top of the file folders. The end fingers must be removed from the slots of the file folder and inserted into different slots to reposition the index tab holder on the file holder. This is a tedious and time consuming work when a number of file drawers require repositioning of index tab holders. An example of an index tab holder having lateral ears insertable into slots in top sections of file folders is disclosed by J. R. Wyant in U.S. Pat. No. 5,311,685. 
     Index tab holders mountable on file folders in predetermined positions determined by slots, holes or protrusions on the top sections of file folders are disclosed in U.S. Pat. Nos. 2,644,089; 3,244,170; 3,238,947 and 3,263,688. A positionable index tab along the top of a file folder having a projection or detent to establish an interference fit on a file folder is described by E. R. Aaldenberg et al in U.S. Pat. No. 6,332,285 The detent can cooperate with holes in the file folder to locate the index tab in selected positions on the file folder. 
     SUMMARY OF THE INVENTION 
     The invention comprises an index tab holder for a document file, note books, and data separation sheet members that can be laterally repositioned without removal of the index tab holder from the file folder, note book and data separation sheet members. The index tab holders have removable transparent sheet members that retain index tabs on the index tab holders. The transparent sheet members can be removed from the holders and replaced on the holders from file folders. The invention includes combined file folders and index tab holders. The file folders have rail and rib members that accommodate index tab holders and allow lateral movement of the index tab holders along the top of the file folders. The index tab holders can be horizontally repositioned on the file folders without removing the tab holders from the file folders.
