Server Utilities :: IMPDP (ORA-31619 Invalid Dump File)

I need to recreate/ clone my database to a new machine. The two machine are not connected in the network.

Step 1. (Oracle 10.2.0.5 AIX 64-bit)
expdp username/password@db1 full=y dumpfile=dp:fpac052912_dp%U.dmp logfile=dp:fpac052912_expdp.log job_name=full_exp

Step 2.
FTP dump files to Windows

Step 3. (Oracle 10.1.0.2 Windows 32-bit)
impdp username/password@db1 dumpfile=dp:fpac052912_dp%U.dmp logfile=dp:fpac052912_impdp.log full=y

I got:
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31619: invalid dump file "C:P7DBfpac052912_dp01.dmp"
