All of the custom messages and dialogs in File.Transfer JAVA support the use of multiple languages through the language parameter. The current version of File.Transfer JAVA includes support for the following languages:

Language	Language Code
Chinese	zh
Dutch	nl
English	en
Finnish	fi
French	fr
German	de
Hebrew	he
Italian	it
Korean	ko
Norwegian	no
Portuguese	pt
Spanish	es
Swedish	sv

Note that in some cases, File.Transfer JAVA makes use of native dialogs defined by the operating system running on the user's computer. The language used for these native dialogs is controlled by the operating system version and locale settings for the user's computer, not File.Transfer JAVA's language parameter.
