Hello,
In the attached configuration I can see following
class-map global-class
match default-inspection-traffic
!
!
policy-map global-policy
class global-class
inspect ftp
But I am not seeing 'service-policy' command so without that policy is not going to be applied and inspection will not run. So use following command in global configuration mode
#service-policy global-policy global
And then check 'show service-policy' command output to see if inspection is in place and is there any packet hitting inspection (after attempting FTP transfer/connection).
Note: Inspection will do its job if FTP communication is not encrypted.
Here is one link for information about FTP/TFTP (configuration on ASA)

I hope this will help.
