The file box is well designed for storing hanging file folders and organizing archived home documents. The handle holds a limited amount of weight and this limits the type of material that can be stored in the file box. Too much weight will allow the handle to slip off the plastic protrusions that hold it in place.
I just have started this different tactic. I have been keeping our medical info in standard files but I think being able to transport to different spots in my home is going to be a big help.
