Enterprise Manager :: Cannot Fully Import Data Pump

I have an 11g data pump supplied by another party.I am on Windows 7(x64).I have experience using other databases, but not Oracle. The complexity of it all is a bit overwhelming...

I downloaded and installed [URL].I used the Database Configuration Assistant to create a database:

Template: Data Warehouse
Name/SID: database0
Password: password0

I then used the 'database0' Enterprise Manager:

Logged in as SYSTEM/password0 (Normal)
Import from Export Files
Entire Files
Host Credentials: myself (am Windows administrator)
All the rest defaults

The job appears to finish successfully.When I look at the schema (using razorsql), most tables seem to be there. However,a significant number are not. When I open data pump in a text editor, those missing tables are clearly there - definitions and data.When I look in the import.log, there are errors of the type:

error in creating database file '/db02/oradata/database0/stuff.dbf'
file create error, unable to create file
unable to open file
(OS 3) The system cannot find the path specified.
Failing sql is:
CREATE TABLESPACE "STUFF" DATAFILE '/db01/oradata/database0/stuff.dbf'

-- followed by the associated table creation errors.

So, does this mean that unix paths are hardcoded into the data pump, and is therefore incompatible with import into a Windows based system? Or are the paths symbolic, internal representations used by Oracle, and these errors are a symptom of an earlier, undisclosed problem?

The thing is, when I view the schema, the tablespace "STUFF" exists, just none of its tables.
