+# provides an easy interface to query what files are currently stored in the infrastructure data server.
+# You can list all files sorted by modified date or size of file, and query based on date modified,
+# user who last modified the file,  parentUri or filename. The output provides the size of each file, 
+# so that you can check the space being used to store files. 
+# Use this tool to view files managed by the files service and stored in the infrastructure data server.

+# For example, if I want to see all potential log files, 
+# created by the /jobexecution service that are older than 6 days old.
