Probably many familiar with the situation, when you bought a new hard drive for your PC, and then, a short time later, suddenly surprised to notice that it is filled almost completely. What should I do in this situation? You can buy a new disk, but better just to free up space on the existing drive: Remove unnecessary files and programs, and films, music and other data is moved to external media. It remains only to solve the problem: how to find the largest files? Make it better with the help of the program performing Disk Usage Analyzer, for example, such as the Disk Usage Analyzer. It will scan the disk and displays a list of all files and folders on it, their size and last modification date. With this simple free utility, you can see the list of the hundred largest files in a specified folder, or in the specified drive, which is very convenient when you free up hard drive space.
In this age of computer technology, even schoolchildren know that all the information on the hard disk is stored in a file. These files managed by the file system. If the user needs to perform some action on the file, the operating system sends a request to the file system, which does that have to do with a file - open it, edit, and so on. If you purchased your hard drive, you can not just plug it into the computer and immediately work with him. The disc must first be formatted by setting the filesystem, ie split it into individual cells (clusters), in which the file is recorded, and either alone or it is broken into pieces and stored in adjacent clusters. This file has been broken file system, and it also collects the image of the individual parts when you open it.
There are several file systems. Currently, the most widely used two file systems - NTFS and FAT32. FAT32 - an old system, it is used less and less, yielding its position more convenient system NTFS. NTFS -more reliable system, it can automatically recover from some disk failures. But its main feature - it's data security. It allows you to deny users access to individual files. The FAT32 file is located in the section that is formatted with the file system, are visible to any user who has access to your PC. In addition, you can not create a partition in FAT32 volume larger than 32 GB, and the maximum size of a single file in this case is 4GB. Using the FAT32 file system is sometimes justified, if you need to install any operating system earlier versions such as Windows 95 or Windows 98, in other cases the system is NTFS.
