@PlagueHO any update on this and #279 ?

[bbonaby]

Thanks @PlagueHO I'll update the PR based on your suggestions

[PlagueHO]

Sorry about the delay @bbonaby - I'll get back to your comments in the weekend.

Hey @PlagueHO I plan on updating this PR today. If possible would you be able to hold off until I update it? I've gotten rid of the 'UseUnallocatedSpace' and would like you to take a look at a different approach I did without needing that flag. Thanks

@PlagueHO any update on this? Thanks

Should we separate this out into a common function? E.g., a "Compare-PartitionSizeUsingGB" - or something? This is also because the same functionality is used in `Set` as well.

I created a generic function called Compare-SizeUsingGB so we could reuse the same functionality here. Thanks
