Portuguese Guitar Sample for Yamaha

Hello everyone i need a sample with the sound of the Portuguese Guitar and i can't find it anywhere for download, can someone help me? PSR-Sxxx compatible,
This sample exists and i know where it is, but i cannot use it because it's an Expansion package directed just for the PSR-SX series And Tyros not for my keyboard but almost all the samples from SX series and Tyros, are compatible with PSR-Sxxx Series, you can find this package on the Yamaha Official site, there you will find several packages by country for those keyboards, But if someone has installed it could send it to me and these samples are free. if you have the expansion installed on a device, you access to extract the sample and store it in a PEN or PC. This format is campatible with my keyboard. I use a lot of samples for Tyros and other Yamaha Keyboards As an IT Specialist i know this is possible, i just need the sample, not the package. This package it's imposible to install on my keyboard.
