File output plugin permission denied

This is my output configuration, right now i am just using grok to parse out IP and a WORD

input {stdin {} }

filter {
grok {
match => {"message" => "%{IP:user_ip} %{WORD:computer_name}"}
}
}

output {
file {
codec => json
path => "H:\logstash\logstash_outputfiles"
}
}

EACCES: Permission denied -H: logstash/logstash_outputfiles initialize at org/jruby/RubyFile.java:370

Is H:\logstash\logstash_outputfiles a file or a directory? Judging by its name it sounds like it would be a directory, but the path needs to be a file. I'd also try using forward slashes instead of backslashes. And, obviously, make sure the user that Logstash runs as has write access to the file in question.

thank you, you were right, i specified a directory instead of a file
