logstash file input plugin can't handle multiple files within a directory on Windows?

I have a folder that has all the log files I want to process, but nothing got directed to elasticsearch when i do

Input{
file{ path=>"C:Users/Desktop/logs/*.txt"
start_position => beginning}

but works when I do

file{ path=>"C:Users/Desktop/logs/log1.txt"
start_position => beginning}
The first works on Mac but doesn't on Windows, any fix?
