File transfer from windows host to ESXi Server

Can alnyone tell me the process for transfering a file from a network share to the ESXi Server?  I need to update the raid controller bios.

the informaiton I have found so far says to use the following command but I can't seem to get it to work.

scp <file name> root@10.10.10.10:/tmp  where  10.10.10.10 is the IP address of the ESXi server.

Thanks!
