When the maximum local disk usage is approached, files are purged by selecting the oldest files first. This limit may be exceeded temporarily by the maximum log size because the active file will not be purged. Size is specified in megabytes.
Setting to any integer less than 1 will disable pruning by disk usage.
Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
