For volume: (C:)\\?\Volume\{a488ed41-38e8-11de-abc2-806e6f6e6963\}Shadow Copy
Storage volume: (C:)\\?Volume\{a488ed41-38e8-11de-abc2-806e6f6e69
63\}Used Shadow Copy Storage space: 5.547 MB (0%)
Allocated Shadow Copy Storage space: 1.5 GB (3%)
Maximum Shadow Copy Storage space: UNBOUNDED (100%)
As you can see, in this example only 5.5MB of space is being used by the snapshot, and there's no maximum to the amount of disk space usable by shadow copies.
