Another possibility would be to add a native method to the test itself to invoke [GetDiskSpaceInformationW](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getdiskspaceinformationw) to obtain the value of `CallerTotalAllocationUnits` (in bytes) from the [DISK_SPACE_INFORMATION](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/ns-fileapi-disk_space_information) structure.
