Relative Paths './' and '../'

Hi everyone,

When using relative? paths does anyone know the difference between './' and '../' ?

. refers to the directory you're currently in
.. refers to the directory above the one you're currently in

Thanks Spork,

Say in this example there isn't any difference between them?

If the webpage is in the root and the images are in an 'image' directory in the root.

Line number On/Off

Code: Select all

1.  
2. <img src="images/icon_link.png" alt="" width="22" height="22" />
3. and
4. <img src="./images/icon_link.png" alt="" width="22" height="22" />
5.  

Why would you bother using './'?, for include files or something?

Thanks

I can't find a good use for './' in included files either?
Can anyone enlighten me as to when they would use './' ?

Maybe just an operating system relic from before there were browsers ?

Maybe, I don't really see a use for it..

In older shells for UNIX/Linux systems, the dot was sometimes required in order to execute a script in the current directory. It really has no use in modern shells and is virtually unnecessary in URLs.

I doub't you need to worry about that thing anymore. It's gotten more modern now

I still use that sometimes with my .net apps actually ... very rarely though ... something like

Line number On/Off

Code: Select all

1. Server.MapPath("./")

gives me the current directory on my host ... so if I want to create folders on my root I'll use it like

Line number On/Off

Code: Select all

1. Server.MapPath("./" & FolderName)
