Referencing a file in flash - File Heirarchy

Here is my question. I know the basics of referncing files absolutely and relatively. But I heard there are other ways to do it in flash.

For example:
…/ = parent folder
/ = site root

and I heard that

./ = location of swf file

I do not know if that works, I have tried it but to no avail. So does anyone know how to reference the folder that the swf is in realatively when the flash file is run?

Also, is there a way to reference the folder that the page running the swf file is in.

Thanks for any help!
