Web.Link Export to DXF Uppercase file name

Hi,

Does anyone have a solution when exporting a drawing to .DXF format via Web.Link, the file name is always written in lowercase letters. How to get the file name to be written in uppercase letters.

Part of the code is as follows:

...

var DXFOut = pfcCreate("pfcDXFExportInstructions").Create();
CurModel.Export(FileName.toUpperCase(), DXFOut);

...

No mater what I always get filename od disk written in lowercase.,But if I export to PDF format I can get in uppercase format.

Any idea, solution?
