ZCM 10.2.2 SLES 10.2

QUAD NIC'ed 16 gigs of ram. Uploaded a 300K exe and a DAT file on Friday. It is now Tuesday and my conent is unavailable.

Being that one of the files is a .dat file, my question is (a) is this file extension allowed in ZCM repo and (b) why is my exe file still not available??

Thank you for any help you can provide.
