This particular problem could also be caused by the leading space...

display subinstr("`c(current_date)'"," ","_",.)
_8_Oct_2013

You don't spell out which file you are looking for here.

Your code segment implies that `c(current_date)' is being expanded as
8 Oct 2013, which is entirely in order.

Otherwise, I don't believe that you give us exactly what you typed as
it is hard to believe that

file

will be interpreted by Stata as

DFID MT Kiswahili

without some extra quotation marks.

If anything else is hinted by your post, it is that you may be being
bitten by the use of a backslash, which is repeatedly warned against
in Stata documentation. Regardless of operating system, Stata is happy
to work with forward slashes as filename separators. For one version
of the facts, see
