Edortizr6, he's actually talking about samples to be used within FL, through the use of a 'sampler' instrument. Go to insert a new instrument and insert either 'Audio Clip' or 'Sampler' then look in the instrument window under the smp tab I believe it is, and you should see a file path and a folder icon. If you click on the folder icon, it should allow you to locate the samples in question here.

For more information about audio clips, see this tutorial:

Hope this helps!
