To specify relative pathnames in links you must use UNIX-style paths regardless of the system you actually have. You therefore separate directory or folder names with forward slashes and you use two dots to refer generically to the directory above the current one . . Table shows some examples of relative pathnames and where they lead. TABLE Relative Pathnames Pathname Means href is located in the current directory. href files is located in the directory called files and the files directory is located in the current directory. href files morefiles is located in the morefiles directory which is located in the files directory which is located in the current directory. href . is located in the directory one level up from the current directory the parent directory . href . . files is located two directory levels up in the directory files. If you re linking files on a personal computer Macintosh or PC and you want to link to a file on a different disk use the name or letter of the disk as just another directory name in the relative path. Absolute Pathnames You can also specify the link to another page on your local system by using an absolute pathname. Absolute pathnames point to files based on their absolute locations on the file system. Whereas relative pathnames point to the page to which you want to link by describing its location relative to the current page absolute pathnames point to the page by starting at the top level of your directory hierarchy and working downward through all the intervening directories to reach the file. Absolute pathnames always begin with a slash which is the way they re differentiated from relative pathnames. Following the slash are all directories in the path from the top .
