Different Paths
Be sure to understand the difference between relative and absolute file paths. An absolute file path, will include the root directory, shown either by the Uniform Naming Convention (which begins with backslashes \\, and is followed by the computer name, drive, or server\shared folders\ and actual file), or a path beginning with a drive letter followed by a colon and a backslash. So an absolute file path can be either of these:
\\server\nyc01\user1\Documents\ABC Inc\Index.xlsx
F:\Documents\ABC Inc\Index.xlsx
A relative file path will just show a file name and a folder - or the current working directory of the file. This kind of file path will begin with two periods and can either only indicate that a file is in the current directory on drive, server or computer, or in a specific child folder in the current directory. Examples of a relative file path are:
..\Index.xlsx
..\..\Index.xlsx
..\ABC Inc\Index.xlsx
... and naturally if you have a path to a file on the internet, such as
http://www.aceds.org/page/certification/Index.xlsx
. .. you have a URL, a Uniform Resource Locator.
