PrimaryVolumeSpaceAvailable property

The installer sets the value of the PrimaryVolumeSpaceAvailable property to a string that represents the total number of bytes available, in units of 512, on the volume referenced by the PrimaryVolumePath property.


For example, if PrimaryVolumePath is set to "D:", and volume D: has 446,134,272 bytes free, PrimaryVolumeSpaceAvailable is set to 871356.

Note if this value is to be displayed within a static Text control, the FormatSize bit can be used to automatically format and label this number in units of kilobytes or megabytes as appropriate.
