You can't access file outside the sandbox with mql5 (even with DLL).

For security reasons, work with files is strictly controlled in the MQL5 language. Files with which file operations are conducted using MQL5 means, cannot be outside the file sandbox.

Thanks.

But, is that any solution for this?

I want copy file outside by using MT5.
