Windows Server 2003 R2 SP2 - physical server, local disk
There's a large difference between what Windows and TreeSize show for used space on one of my disk partitions. The properties in Windows shows 106 GB of used space, but TreeSize only shows 19.3 GB of used space. Almost an 87 GB difference. TreeSize is displaying all hidden files and protected OS files. I also added together all the file sizes myself and my result matched TreeSize.
Does anyone have any idea what could cause that? Could Windows be seeing something that TreeSize is not?
