The mess does not know of drawers and much less of those that have labels so that you put name in each drawer. Those that have file cabinet with wheels do not know borders, since they slide easily wherever you want. Those that have finished back do not know wall that covers them, because they look great in any place. With open or closed drawers, look that they have ideal size according to what you want to keep inside, folios or other things.
Buy yourself a file cabinet with wheels that has been invented for that; invest in one of most useful office furniture items that will earn you more time and money. Locate files is fast and very comfortable, as well as save documents and orders in each file. Usually it is a usual excuse not to keep files in a file cabinet that if you do not have them in sight, you forget to do what you have to do with it: writing, a resource, minute it etc.
But do not have all files on table. You take out one you are going to use and when you finish you save it in file cabinet with wheels and cross out task in list. I also do a general review of issues every month. I open each drawer and check one by one, situation in which each file is, making a list of tasks of what to do with each file that has some pending action. I also check if signs are recorded in calendar.
