Need help for importing from old to new database

I need to get a new test database, mirror of another database. The test database is created, and I now need to put data in it. I work on Oracle V7 with Unix.

As user 'system', I made a full export of the old one, but I would like to know if I can just import the exported file in the test database :

when I look at the exported file, I can see for instance the statement " create tablespace "toto" datafile
'physical_path_ot_the_tablespace_file_on_the_old_database'..." and so on.

Anybody could help me to say how it works ?

Thanks in advance
