When specifying the location of a file or directory, you can use an absolute path, a relative path, or a UNC share path. The following are acceptable paths to a file: 
 I suggest using the @ string literal for path or file names so that the string appears neater. For example, instead of c:\\expt\\loveletter.txt, you can use @"c:\expt\loveletter.txt".
Table 18.3 shows the methods to use for performing copying, moving, and deletion of files. Code examples are given later.
