How to organize office files
Create file categories.
The first thing to do if you want to organize your files is decide what major categories you will use for sorting. Different kinds of offices will have different kinds of categories, but the general system is the same.
You need to figure out a system that sorts your files in a meaningful way. For example, if you work in a law office and need to organize client files, you might sort by general case types: litigation, probate, corporate, administrative, and others.
