True or False? Icarus only cares about the original copies of his files.
True or False? Icarus only cares about the original copies of his files.
This statement is not true.
This statement is false. Icarus keeps both "hard-copies" and "back-up" files of all of his documents. This is a good indication that he is concerned both with the original documents, as well as the extra copies of his files. A "hard copy" is a physical copy of a document or file which exists on a machine as well. A "back-up file" is an extra or emergency copy of a document or file saved on a computer.
