I disagree. I expect those " " are there precisely because you put them there. If previously to this you had 

. local data `""example.dta""' 

then you are insisting that the " " are part of the macro, not delimiters. Re-define 

. local data example.dta 

and everything should work.

I think there is something weird with the extended function of the macros:
If I type,

macro dir
_data:          "example.dta"
_dir:           C:\Temp

Notice that macroname data is enclosed in double quotes while the
macroname dir is not.

how can i get with macros the following path: "C:/Temp/example.dta"
???? I tried the forward slash instead of the backward slash and I
still got an error:

use "`dir'/`data'", clear
invalid 'example.dta'


Thanks,
