As it turned out the cleanup_hso_files script was failing due to an entry present regarding FPM HSO… which isn’t supported for the customer’s current version. So /hekimian/pmint/users/ftp/pub was not being cleaned out.
Corrected cleanup_hso_files script (minus the fpm entry) is located under
C:\Hekimian Docs\Useful Scripts (PC) and /hekimian/pmint/appbin (Host)
