Modifications exist only virtually, which means you're only seeing a preview of what will happen if you save the changes, but nothing is actually set in stone yet. Changes don't take effect until you click the Execute button. Managing the size of a partition in EaseUS Partition Master is dead simple thanks to their easy-to-use slider that lets you drag left and right to shrink or expand a partition.Ĭhanges you apply to a partition with this program aren't actually applied in real-time.
