Ask PC Experts - File Systems

A file system:

  1. Specifies the names for the files/data.
  2. Makes efficient use of the space available in your system.
  3. Specifies the path to the directory or file the data is stored in.
  4. Stores and retrieves data efficiently
  5. It is the hardware used for nonvolatile storage.
  6. Controls the hardware and the architecture of the software and the hardware of the system.

Most commonly used file systems are as follows:

  • · For Windows 2000 and NT (NTFS)
  • · For MS-DOS (FAT)
  • · For Windows 95 (VFAT and FAT32)
  • · For Macintosh (HFS and HFS+)
  • · For UNIX (UFS)
  • · For CD-ROMs - ISO 9660

Types of File Systems:

  1. Disk File Systems – designed for storage on data storage devises like disks connected to the system. E.g. NTFS
  2. Flash File Systems – a system designed for storage of data in flash memory. Flash memory is non-volatile computer memory that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products like mobiles.
  3. Database File Systems – designed to identify and store files as per their characteristics.
  4. Transactional File Systems – designed to prevent loss of data due to sudden shut down of system due. E.g. due to power failure.
  5. Network File Systems – designed to get access to files available on the server.

Thus, with various types of file systems available we can access our data easily at any given point n time.
