No confirmed format, vendor, or software association is available for the .es_ file. Its contents and purpose therefore cannot be determined from the extension alone.
Because there is no documented format information for this record, the extension should not be associated with a particular operating system, application, or file type.
No specific program is known to open the .es_ file. It should be opened only with the application that created or supplied it, if that application can be identified.
No reliable conversion method is available because the format of the .es_ file is unknown. Conversion requires identifying the file's originating application and using that application's own export options, if available.
