Not that I know of without a plugin. Filefire from Dacons is the one I use for this sort of thing but the plug in from Troi and others will probably do this as well.
I use the free BaseElements plugin for exactly this:
You would use a calculation like this:
BE_SelectFile ( "Please select a File!" )
which returns the path to the select file.
If you're after a folder then use:
BE_SelectFolder ( "Please select a Folder!" )
which returns the path to the selected folder.
