Many users know the situation when your hard disk is almost no free space. What should I do in this case? It is quite obvious two options to solve this problem: to buy a new hard drive, or free space on the volume that is currently in use. As experience shows, a new hard drive has the ability to relatively quickly clogged again with different information. It is better to choose the second path - to clear space on an existing hard disk: delete unnecessary files and move files to another location, that take the maximum amount of disk. How to look busy than the hard drive? For this purpose, you can use the Disk Usage Analyzer, which performs analysis of hard disk.
Not all new users know that if you do decide to buy a new hard drive, then before you start using it, you need to format the disk and divide it into partitions and logical drives. Often the drive is divided into two sections - primary and secondary. The main section of the operating system, an additional section - all other files. Sections are logical drives with their names, for example, drive C, drive D, and so on. After disk partitioning and logical drives being formatted, that is the logical layout of all disk space.
On the physical level hard disk divided into tracks, which in turn are divided into sectors. The sector - which is the minimum amount of physical disk for data. Typically, its size is 512 bytes. When marking is performed logical disk thereon are separate parts, which consist of one or more sectors. They are called clusters. The number of sectors in the cluster, and, consequently, its size can be adjusted when formatting the disk. The cluster size affects the amount of which is occupied by files and the speed of the system. This is because if the file size is less than the size of the cluster, then the cluster can not be anything else to add, with the disk space consumed irrationally. On the other hand, if the cluster size is small, the file is written to the plurality of adjacent clusters, and if adjacent clusters is not enough, the remaining part of the information written in the next free cluster. In this case, it increases the time it takes to "build" file of the individual clusters and the speed of data exchange with the hard drive is reduced.
