The up to sim size is how much ram fumefx would use to sim if it was using all the voxels (ie, with adaptive grid off or with the adaptive grid filling the whole fume grid)
Render size is how much ram needed to render a full grid (will depend on how many channels you save out, eg just smoke will be smaller than smoke and fire and fuel etc.) Handy if you have say a 16gig Sim machine but need to render on 20x 4gig machines or something.
Memory used is just what it is! Dependent on voxel size mainly.
Size on disk will depend on how many channels you save out and and grid size will go to about x10 if you turn on fluid mapping.
Snapshot will just dump a full sim file saving everything needed to continue a sim or do an initial state every 10 frames (or what ever you specify). Dont use it much so could be wrong. Never had much luck with snapshots so have just turned it off to save time and space.
Ability to continue will let you dump one of these files when you press "Stop" rather than cancel while you are simming and then you can change settings and continue if you want.
Look at the "up to simulation size" for your ram usage, dont forget to accommodate for ram used by the OS and Max. If I set it to about 3000 I find it will stay under 4gig OK.
