Hi there, are 3D Stager save files self contained?

I am setting up a scene to render on my iMac in my office, but the high resolution render keeps crashing after a couple of hours (and Stager 3D doesn't seem to have a recover/resume function).

If I want to send the scene down to my beefier Windows machine in the basement (to maybe even render on the GPU if it's supported), is the save file all I need if I have imported models/textures/materials in the scene? Or do I need the whole folder hierarchy to be reproduced with all of my imported stuff in it?

Thanks!
