File and folder locations are important to Autorun projects.
Those file and folder locations often vary from the development
environment to the CD being created. Additionally, the folder
structure of both the development environment and the CD will
likely vary from the machine on which the program will be
run. Not considering relative and absolute paths can have
an adverse impact.
|
An absolute path is the most commonly seen and used
type; it explicitly states the drive, the folder (or
folders) and conditionally a filename.
Examples:
C:\my documents\myfile.txt
C:\windows\temporary internet files\mygrahic.gif

A relative path is an implied path. When a command
is expressed that references folders or files (or folders
and a file) the current, working drive and directory
is the implied path. Therefore, a relative path is stated
in relation to the current, working drive.

 |
| Example 1 |
| mygraphic.gif |
This .gif file is in the current directory. |
The current directory is designated by:
(name), (.\name), or (name\). |
| .\mygraphic.gif |
(This means the same thing as the one above.) |
|
| mygraphic.gif\ |
(This would be another way of saying the
same thing.) |
|
| Example 2 |
| ..\mygraphic.gif |
This .gif file is back
one directory from the current directory. |
To move back a directory
another period or the name of the directory must be added
before the current directory’s name: (..\name) or (new\name).
|
| Example 3 |
| \windows\mydocuments\ mygraphic.gif |
This is a little tricky- to access the file,
we have to back up to the Root directory and then follow
the path. |
Paths starting with a backslash (\) mean
that the Root directory must be accessed first to follow
the path. |
