06NTFS File System Introduction

NTFS is widely used in Win 2000 start

Only partitions can meet the specifications of the file storage, even if only one partition is partitioned, such as the home bought 160 flat I have to press the function of the house into a room

One is to manage the disk, one is to manage the files on the disk

Distinguish between the need to format, which is defined in the file system, the format is divided into pieces of

The concept of this little lattice inside the disk is called cluster

So the cluster is not very good, because the FAT32 will increase as

Can the cluster size be selected?

See Win Server 2008 backstage there are several hard disk ways above

Operate as on 08DC

After the format is good, the computer will be more default a partition, write a file on the D disk

That's why 4KB is occupied, files are 15 bytes.

Conclusion: The volume of files is very small and the most wasted disk space

Cluster small to ordinary switching clusters, the impact of efficiency, cluster large also wasted

General 4KB does not need to change, Microsoft after the frequent test results

Because of the single color, and the compression after the startup effect is slow windows, can not use as much as possible, the disk color will become blue and green

More secure, file server, NTFS with security permissions

FAT32 single file more than 4gb,u disk may also FAT32 storage only 4GB

Creating a folder by default inherits the partition permissions of the D drive (corresponding partition disk)

When we assign permissions to a folder, subfolders and files in this folder are all inherited.

Accumulation of permissions

Refusal priority: In fact, the reason is the ACL

What are special permissions?

Indicates more precise. Read permissions can be further subdivided
