There is a A.DBF file at hand. How to make its modification time be the current time? First, I wrote BREAK >A.DBF But the format of the DBF file was cleared.. It's not a database file anymore. Then I changed it to BREAK >>A.DBF... The modification time didn't change again.. May I ask how to solve it? [ Last edited by simplenoughappy on 2008-2-21 at 06:34 PM ]

See someone's one E: CD E:\1 COPY A.DBF+; can be realized.... But if you directly write the path in COPY, there is no change.. May I ask why?

I think so: Copying a.dbf to c:\a just simply copies the file from one path to another, and of course the time attributes of the original file are also copied over. And Copy a.dbf+; is another usage of the copy command. In fact, it is equivalent to appending or modifying, so its modification time will naturally change.
