Apparatus having function of checking error in copying or moving file and method thereof

1. An apparatus having a function for checking an error in copying or moving a file, comprising:

a first storing unit to store first data to drive the apparatus;

a second storing unit to back up the first data from the first storing unit as backup data; and

a controller to detect an error in the backup data after backing up the first data from the first storing unit to the second storing unit,

wherein the controller creates a variable in the second storing unit and changes a name of the created variable to be identical to the first data stored in the first storing unit after backing up the first data from the first storing unit to the second storing unit if the error is not detected in the backup data.

2. The apparatus as recited in claim 1 , wherein the controller detects the error in the backup data in the second storing unit through a cyclic redundancy checking (CRC).

3. A method for checking an error in copying or moving a file, comprising:

creating a variable in a second storing unit;

moving data stored in a first storing unit to the variable in the second storing unit;

inspecting the moved data in the second storing unit to determine whether an error is in the moved data; and

changing a name of the created variable to be identical to the data stored in the first storing unit if the error is not detected.

4. The method as recited in claim 3 , wherein in the inspecting of the moved data, a cyclic redundancy checking (CRC) is performed to detect the error in the moved data.
