File Upload Control on C#

Afternoon Everyone

Please help with File Upload Control,
This is the error that I am getting

The Microsoft Jet database engine could not find the object 'c:\windows\system32\inetsrv\Maskwe.xls'. Make sure the object exists and that you spell its name and the path name correctly.

I have browsed for this path "C:\Users\USER\Desktop\Maskwe.xls" but is pointing to a different location which is 'c:\windows\system32\inetsrv\Maskwe.xls'. Im not sure why is doing this.

This is my code:
string strCommand = e.CommandName.ToString();
int intRowIndex = Convert.ToInt32(e.CommandArgument);
int intBSID = Convert.ToInt32(dgvPubOrderPerBS.Rows[intRowIndex].Cells[1].Text.ToString());
Button bts = e.CommandSource as Button;
if (e.CommandName.ToLower() != "upload")
FileUpload fu = dgvPubOrderPerBS.Rows[intRowIndex].FindControl("FileUpload1") as FileUpload;
if (fu.HasFile)
string strFullPath = Path.GetFullPath(fu.PostedFile.FileName.ToString());
string strExt = Path.GetExtension(fu.PostedFile.FileName.ToString());
string strFileName = Path.GetFullPath(fu.PostedFile.FileName.ToString());
importdatafromexcel(strFullPath, strFileName, strExt, intBSID);
File Upload control are in a DataGridView (dgvPubOrderPerBS).

Thanks in advance
