Data File is an important part of computer that stores data which are used by the computer application. It does not have those files that contain ns codes (typically known as program files), instruction, and those files that provide information about operation of system. But it contains specifically those information which that uses input or is used as written output and used by other software program. This is especially used in the situation when the debugging of a program is required.
But there are situation in which data files become corrupted and the reason of this corruption generally occurs due to damage in hard drive or diskettes, conflict of software, improper shutdown, voltage fluctuation, So if the hard disk is improperly maintained then corruption occurs and due to this reason files lose its integrity and becomes unable to be accessed and two or more files occupies similar space on the hard disk. It does not mean that everything is lost but it can be repaired and then user can access the lost files again by restoring them with available updated backup.
