Claim:
A portfolio comprising: a body having a receiving space defined therein, a backside of the body having at least one sliding groove defined therein; an upper cover being a foldable sheet for sealing the receiving space of the body; and at least one connecting unit each includes a T rod, the T rod simultaneously passing through the at least one sliding groove defined in the body and the upper cover so that the upper cover is slidable along the body via the T rod; wherein when the upper cover is unfolded, the upper cover slidably moved downward along the backside of the body by sliding the T rod along the at least one sliding groove, such that the upper cover is concealingly disposed on the backside of the body to completely unseal the receiving space; and thus the user may take the object in the portfolio easily and freely without being affected and interfered by the foldable upper cover.
