The file system operating system is responsible for storing the information logically into small blocks attachments, so users know as normal files. These small blocks can be easily manipulated by the operating system, which allows the user to cut, or carry information in small blocks, making the process much easier and simpler to understand.
Each operating system has a different file system , and each has its advantages and disadvantages over others. In addition, certain file systems that are designed for a specific purpose, such as servers that make extensive use of read / write operations in a small time interval, so you need high efficiency with the least cost in terms of resources consumed.
In early versions of Windows , this operating system had the FAT file system , which is based on the allocation of files using a table or General Index , which tells the operating system on which sector of the hard disk file is located. A major disadvantage of this type of file is that if the table becomes corrupted then the files are lost because Windows does not know what the hard drive is stored the blocks.
Later, Microsoft decided to incorporate NTFS file system, which is used to date. This system offers advantages over FAT, for example, the ability to store much larger files, or large volumes of information between different devices. From Windows XP this format became more popular and has been widely adopted by large numbers of users.
The UNIX-based operating systems, use some hierarchical file systems, which generally have better performance than NTFS systems. While most Linux distributions use a file system EXT2 or EXT3 , Mac operating systems use HFS system, which is considered a hierarchical file system.
Other types of file system as the ZFW designed specifically for the business environment and the servers because they provide quick access to information at low cost in resources and energy, however, adoption of such systems is not so great due to the sector of the population has been addressed.
Most applications that are responsible for recovering deleted files, contains a very good support for different file systems. Whether hard drives formatted with FAT, NTFS, EXT or HFS, all can be analyzed and dealt with those applications. There are cases that require special supplements to read partitions that are in a different format.
