Have you tried to run the command inside the directory where the dmp file is located? Or even put the directory path between ''?
cd C:\oracle\export
imp mbbank/xxxxxx FROMUSER=c##cuongnguyen TOUSER=mbbank file=cuongnguyen-user.DMP
or
imp mbbank/xxxxxx FROMUSER=c##cuongnguyen TOUSER=mbbank file='C:\oracle\export\cuongnguyen-user.DMP'
Just for your knowledge, oracle has a more improved database export and import tool: expdp and impdp. And you can do it in your own way:
Creating a directory of export inside database:
$ORACLE_HOME/bin/sqlplus '/ as sysdba'
SQL> create or replace directory export as 'C:\oracle\export';
Exporting the schema:
expdp mbbank/xxxxxx dumpfile=cuongnguyen-user.DMP directory=export schemas=c##cuongnguyen
Finally importing as a new user:
impdp mbbank/xxxxxx dumpfile=cuongnguyen-user.DMP directory=export schemas=c##cuongnguyen remap_schema=c##cuongnguyen:mbbank
