Hi Ivica,

Are you sure that is the correct file path? Can you do what is requested in the FAQ and show exactly what the error produced by Stata is?  This will help to better understand what may be causing the error.  You could try:

cd `"F:/project/data/"'
ls

To see what files are in that directory and verify that the files of interest are located there, but you've provided very little information that would make it easy to help you with this issue any further.

HTH,
Billy
