Extra property for unknown data.

A String value.  

object.Extra3 [= value]

The Extra3 Property syntax has these parts:

Extra properties have no specific usage in wodFtpDLX. They are here only to provide any potential information that cannot be put in any other property contained inside DirItem object. In general, you can use them to store data you might want to assign to some item.

There's one use of Extra1 property in wodFtpDLX at this point. During parsing of received directory listing, some servers will return something called 'nlink' value (number of links for the file) which cannot be put in some other property (and usually this is not significant value). It is placed in Extra1 property. Others are left empty.

Just a reminder - you must call ListDir to get directory listing, and then access files through Ftp.DirItems property in order for this property to be available!
