Thank you very much for the help.

I have tried what you suggested but unfortunately it seems it is not my problem, the file test2 is empty. And I have already tried open3 to get the same result than open2... Maybe it is something with windows, I have read some stuffs about it. I think I will try with a com file, maybe it will work. I'll let you know.

I have looked at the program and processes section but I guess I will give it a closer look. :)
