Does anyone know where to get hanging files folders and interior folders? I just relocated here from the U.S. with my family and am trying to keep our papers organized and i just can't get with the concept of L folders and plastic clamshell cases to keep the myriad of papers we have (tax stuff, receipts, school registration, etc) organized. Maybe i just have not come upon the right stores? Surely businesses here use filing cabinets? Thanks in advance.
