I added the Traditional Chinese (Taiwan) translation.
It is available for download here: http://sourceforge.net/projects/icopy/files/Language%20files/1.4x/zh-TW.zip/download
Download the file and extract the content into icopy folder, then restart iCopy and set the language in the settings.
I wish to thank the user who sent me these translation. Thank you all for your support! Stay tuned for iCopy 2.0!
