File folder

A file folder comprising:

• a faceplate having a middle faceplate, a first and second side faceplate connected at both sides of the middle faceplate;
• of which, there is a folding line between the first/second side faceplates and middle faceplate, such that the first/second side faceplates can be folded in relation to the middle faceplate;
• and a corner is defined onto the first/second side faceplates of the faceplate, whilst a flange is defined onto the middle faceplate;
• at least a snap-type combined plate, snapped securely onto local position of the faceplate;
• said snap-type combined plate comprising:
• a first snapping plate having a first abutting surface for abutting onto the side surface of the faceplate;
• a second snapping plate having a second abutting surface for abutting onto the other side surface of the faceplate;
• the second snapping plate is aligned correspondingly with the first snapping plate;
• at least a coupling portion, allowing to couple securely the first and second snapping plates;
• snap holes;
• set correspondingly onto the faceplate for assembly of snap-type combined plate;
• the snap holes penetrate two side surfaces of the faceplate, allowing for insertion of the coupling portion of the snap-type combined plate;
• of which, the faceplate and snap-type combined plate are made of different materials.
