Question 1D: File Management Read the section on File Management in the textbook (pages of the fifth edition and pages of the fourth edition). Apply what you have learned about file management to the exercise that follows. You started a new semester at school and are given a new computer to use. You never kept your files and folders organized on your old machine, but now you are determined to do a better job at keeping your files organized. You know you need folders for each of the subjects you are studying. For each subject, you ll need to have folders for homework assignments, lab assignments, research papers, study guides, and any other information as necessary. In addition, you need folders for the MP3 files you will listen to when you re not studying, as well as a folder for the digital pictures you ll take for personal and academic reasons. Determine the file structure you would need to create to accommodate your semester studies. Start with the C drive and assume that Classes, Pictures and Music are the default folders for class information, pictures, and music files respectively. Show your file management structure on the next page. Be sure to include names for folders, names for sub-folders, and filenames. Also include the appropriate file extensions for all files (10 points total). CS10001: Computer Literacy Homework Assignment #1 (D. Reed) 5
