Constant	Type	Value	Comment
_o_4D Interpreted desktop	Longint	2
_o_Extras folder	Longint	2	Folder with customized contents downloaded to each client machine. Compatibility Note: Beginning with version 11.2 of 4D v11 SQL, it is no longer advisable to use the Extras folder for customized communication between the server and remote machines. It is now recommended to use the Resources folder for this purpose (see the description of the current Resources folder below). The Extras folder is nevertheless still supported by 4D Server so as to maintain the compatibility of existing applications. Note: If the Extras folder does not exist for the database, executing the Get 4D folder command with the Extras folder constant will create it.
