Copied file from HDFS don't show in local machine

I copied a folder from HDFS to my local machine using the following command:

hdfs dfs -copyToLocal hdfs:///user/myname/output-64-32/ ~/Documents/fromHDFS

But I can not see any file in fromHDFS folder and also when I try to run the command again, it says "File exists". Any help is really appreciated.

Thanks.
