Enable this option to allow Undelete to automatically adjust the size of the Recovery Bin when the free space level becomes critically low on the disk volume where it resides. If the amount of free space becomes critically low, Undelete automatically detects this low free space situation and reduces the Recovery Bin size. Meanwhile, it automatically starts purging the oldest deleted files in the Recovery Bin. When more free space becomes available after the purge, the Recovery Bin will automatically re-adjust its size back to the original size setting. You can select the critical free space threshold (for example, 20% of the available free space) and Undelete will adjust the Recovery Bin dynamically as the free space availability changes on the volume.
