A folder for receiving documents or the like is formed from a corrugated board or paper blank, which is folded for forming a front sheet and a back sheet. For the retaining of the front and back sheets insert elements are used, which are inserted with pins in the open front faces of the blank. The folder can be produced with much less effort and expenditure than known folders and can be constructed as a hanging folder or as a rubber strip folder.
