''Back Up Project'' Shrinks 'Sampler Track' samples to nothing

yes that works…

you can combine macros to do these things, so it super fast:

1.Audio - Find Selected In Pool
2.Media - Reveal In Finder

From here you can copy to a safe place, rename if needed, and drag back into Sampler with lock on.
This way you also have a backup from any cool sounds you made for later use.
I have a big folder with all my Sampler Track samples.
