MCT260-Operating Systems I 8 Organizing Files and Folders Store your document folders and files in My Documents Limit the use of the root directory (top-level folder) to system folders and files Store software and documents (data) in separate folders Do not move, modify, or rename folders that contain installed software

MCT260-Operating Systems I 9 Organizing Files and Folders Limit your folder structure to no more than three levels below the root folder. Subdivide document folders when the number of files gets too large Select folders names carefully Periodically evaluate your current folder structure

MCT260-Operating Systems I 10 File Names OS’s after Win95 (1995) use long file names that are up to 255 characters long and can include most special symbols and characters Early OS’s and current ones like IBM and UNIX still require 8.3 file names (a short or MS-DOS file name) An alias or truncated file name is required for long file names that are used in the 8.3 OS’s An alias is the 1 st 6 characters of the long name, a tilde (~), a number, a period, & the 1 st 3 letters of the extension.

MCT260-Operating Systems I 11 File Types & Extensions The three letter extensions tells the OS what type of file it is so it can open the file in the program that created it. Since the newer OS’s assign a picture or icon to a file the default is not to show the extensions. Some common extensions are shown on the next slide and in the XP book on page 53 A more complete list of extensions is found on pages in the CLI book.

MCT260-Operating Systems I 14 Copy/Move Files and Folders In the GUI –Copy –Cut (Move) Using COPY, XCOPY and MOVE in CLI XCOPY copies not only files but also the directory structure to include empty directories and does a regular copy on large files much quicker than COPY
