HOW TO CHANGE FILE extension (.Lib)

can someone help me to read file extension (.Lib).

  1. when I open the file using HEX EDITOR, which I see there is no writing language like human.
  2. how to convert the file into a language that can be read by humans
  3. Then after the fox then restored again as before

here I attach the file below, partly I delete the file because of the limitations of file upload

Thanks .

Where did you get the file with the .lib extension and what do you want to use it for ?
