File Management Path Statement & Use

Good day,

Quick question about the File Management functionality.

Under File Management (Located in the Directories section), I want to create a "deletion" rule, that deletes files under a number of sub-directories after xx days. Can I use the path statement "/ftp/foo/bar/*"? And If I use this path statement, will this delete only the files with in each sub-directory under ~/bar? Or will this delete all the sub-directories with ~/bar?

Thanks
