Trying to convert multiple .wps to .doc, only works when I use the specific filename cannot use *.wps to select them all

Working in windows, the command

"C:\Program Files (x86)\LibreOffice 5\program\soffice.exe" --headless --convert-to doc --outdir "C:\test\out" "C:\test\filename.wps"

Works fine

"C:\Program Files (x86)\LibreOffice 5\program\soffice.exe" --headless --convert-to doc --outdir "C:\test\out" "C:\test\*.wps"

Does nothing

I have also tried taking the quotes off the input file like such

"C:\Program Files (x86)\LibreOffice 5\program\soffice.exe" --headless --convert-to doc --outdir "C:\test\out" C:\test\*.wps

Still nothing

I’m needing to convert quite a bit of them so was hoping to churn them out quickly.
