Hi Sefano,
   Providing the list of files via CF_HDROP (i.e., a DROPFILES 
structure) is fine, but you'll need to implement the IEnumFORMATETC 
interface (e.g., create a TBasicEnumFORMATETC class), and then return an 
instance to IEnumFORMATETC via the TBasicDataObject::EnumFormatEtc() 
method.  This method is called by Explorer to determine what formats you 
can provide.  The following page provides a rough example that should 
get you started...

See the section "IDataObject implementation."  Let me know if you can't 
get things working, and I'll post an example.

Cheers,
