ABSTRACT:
Provided is a code input apparatus for a computer or a word processor, in which determination is made whether a data file or a document file attached with a file name is prevented from being erroneously erased or from being kept in a confidence, and in the case of the prevention of erroneous erasure, the file name is directly used as a code for the file, but in the case of the prevention of keeping the file in a confidence, a code datum received by manual input is attached to the file, so that a time-consuming and laborious procedure in which a code for keeping a file in a confidence is attached to a file required to merely prevent the same from being erroneously erased can be eliminated, so that it is possible to prevent the file from falling into such a condition that the file cannot be opened.
