Phone Data not showing in computer

recently i got a problem with my Micromax Canvas A76, when i connect it to a PC it charges and shows details of Phone Storage and Memory Card, but when i open them, there shows only one file named "System Volume Information" and no other files appear.

Welcome to Android Central! Do you know if the phone is set to MTP? When you connect via USB, swipe down the notification shade and tap the USB connection notification--make sure it's set to MTP.
