robots.txt help

hello world !!
i got a directory in my site called course foods (space b/w the words)
now i cant modify or delete the space as it will take too long for the files associated to it to get updated.
So how can i write robots.txt for that directory ?

i mean

Disallow:/course foods/
or
Disallow:/course%20foods/

 

If your directory's name if "course foods" than I think Disallow:/course food/ is okay.

 

I think %20 character will be better option to replace the white space ?

 

you try with both the command you wrote.....i think white space may be approved

 

Disallow:/course foods/ would work fine. Crawlers can easily identify the space in between.
