The fastest way to regain space on your hard disk is to flush the cache which these programs dump to your hard disk.

在硬盘上重新获得空间最好的办法是将高速缓冲存储器清空，里面的程序将转移到你的硬盘上。

Cache hard disk controller is a piece of memory chips, with fast access speed, it is the internal hard disk storage and buffer between the outside interface.

For example, hard disk 1gb only sub-district, then the cluster size is 32kb, that is to say, even if a file is only 1 byte long, 32kb storage must also account for the hard disk space, and the remaining space will be where all the idle, so has led to great waste of disk space. greater support fat16 partition, the disk capacity of each cluster is also greater, resulting in greater waste.

例如1gb的硬盘若只分一个区，那么簇的大小是32kb，也就是说，即使一个文件只有1字节长，存储时也要占32kb的硬盘空间，剩余的空间便全部闲置在那里，这样就导致了磁盘空间的极大浪费。fat16支持的分区越大，磁盘上每个簇的容量也越大，造成的浪费也越大。
