When running a "bat" step in an external workspace as such:

node('Windows'){
stage('Stage 3. Test Windows'){
exws (extWorkspace) {
bat 'type linux.txt'
}
}
}

the bat command is ran in my C:\ folder. 

This does not happen when running a powershell step. Could it be linked to the fact that UNC paths are not handled by CMD? If so, perhaps we should offer the possibility to map a drive to the network folder that is the external workspace?
