Hello Tarunraj,
How about specifying your "Directory to Scan" as full path name starting with '/'?
In my test environment, "/home/demo/test/subdir" is working well for the username "demo".
I'm afraid that you missed to include '.' in your "Filter Files by Name" field. "RUN.*" should match with all file names start with "RUN" but "RUN*" matches with "RUN", "RUNN", "RUNNN", ...
Cheers,
Seiji
