I think "type" is used to describe the action like bitting ,beatting. "input" is used like the fill some in,import ect. if I make mistake ,please pick it up to me ,thanks .

You forgot 'to enter...'. I think 'to type' means you hit the keys on your keyboard. It's the manual action. 'Input' refers to the data (/the content). By 'typing a file' you would only count the letters. Or you express that you are busy and can't do anything else at the moment. 'Input data' (without 's') emphasizes your aim (/goal /purpose) rather than your action. You have to get the data into your computer. 'Input a file' means you have to finish a complete procedure (/transaction), like filing a new customer. A 'file' is more specific than 'data'. A file can have a name. A position where it is stored. Data can be one (single) entity of information or more. Much more. Some years ago a 'file' would be a card of paper with all the information about a person or a product. It would have been written on a typewriter. By the way: 'Information' is relevant (/useable) data. While in addition to that 'data' also can be not important (at this moment). In any case I would want to know WHAT and WHY you are typing. 'Data' would not be specific (/exactly) enough.
