"Oracle" imp-00010:not a valid export file, header failed verification

Someone gave an oracle file, the results of the import when the problem was found, the error is as follows:

Imp-00010:not a valid export file, header failed verification

After the online query found that is a version of the database problem caused by using the UE editor to open the DMP file, see the first line as follows:

Indicates that the database version is: ORACLE12C version

Querying the current database version using Sql:select * from V$version

We changed the texport:v12.02 of DMP files to V11.02 and imported again, which solves the problem perfectly.
