Chapter 5: Working with Files and Folders
Chapter 5 Working with Files and FoldersAfter completing this chapter, you will be able to:
Your computer stores information in the form of files. There are many different types of files. Some are used to run programs, some are created by programs, and someare created by you. The files used or created by programs include executable files and dynamic-link libraries (DLLs). These files are sometimes hidden to prevent accidental deletion of important data. The files you create include documents, spreadsheets, graphics, text files, slide shows, audio clips, video clips, and other things that you can open, look at, and change using one of a variety of applications. Files are organized on your computer in folders. When Microsoft Windows XP is installed on a computer, it creates four system folders:
Within each profile subfolder in the Documents and Settings folder, Windows XPcreates three folders:
You shouldn't ever need or want to touch the folders used and created by your programs, but knowing how to organize the files you create is essential if you want to be able to use your computer efficiently. All files have names, and all file names consist of two partsthe name and theextensionseparated by a period. The type of file or the program in which it was created is indicated by the extension. The extension is a short (usually threeletters, sometimes two or four) abbreviation of the file type. By default, Windows XP hides file extensions. If you would prefer to see your file extensions, open My Documents (or any folder) in Windows Explorer, and on the Tools menu, click Folder Options, and display the View tab. Clear the Hide extensions for known file types check box, and then click OK to close the dialog box and apply your settings.
Files also have icons, which are graphic representations of the file type. Depending on the way you're looking at your files, you might see a large icon, a small icon, or no icon. In this chapter, you will learn how to view and manipulate your files and folders. The practice files for this chapter are located in the SBS\WindowsXP\Structure folder. (For details about installing the practice files, see "Using the Book's CD-ROM" at the beginning of this book.)
