There are two ways to accomplish this (that I know of). By copying sounds to the +Drive, and by sending Sysex.
If you want to copy your sounds from the Pool to the + Drive, you first have to make sure you have Stored sounds to the Pool by choosing a track and going to the Track manager to save it to the pool.
Once you have sounds in your pool, go to the Sound Manager (FUNCTION+SOUND) make sure you’re viewing you Pool, select your sounds and go to the Right side menu and choose “Copy To”.
You can then choose either to save it to the first available +Drive slot, or directly to a +Drive Bank.
…and of course if you’re just talking about Sample (not Sounds) then I think you’re just looking at it from the wrong direction - if you have your samples in a folder on the +Drive, just copy them over to that other project…it’s the same one step but from the other direction.
Since Samples are not the same as “Sounds”, once associated with a project you can’t save them to another project nor to the +Drive, cause they are already there.
The only thing you can do is backup the project - which will reference any use of samples, and then create a folder on your computer with the samples you are using in the folder…same names.

If you want to have the same sound pool samples in a new project you can always save that project under a new name and then delete all the sequence data manually. Tedious but it does the job.
