how to restore oracle data backup

Question

Recently, the HD of my computer was having problems. My oracle 10g xe was installed and running in this HD.

But I performed a copy of the DBF files in the folder "oradata\XE", before the HD stop functioning. These files are: CONTROL.DBF ,SYSAUX.DBF,SYSTEM.DBF,TEMP.DBF,UNDOTBS1.DBF,USERS.DBF

I wonder if is possible to recover my data from these files. Or, if is possible to import the data in this files to a new installation of Oracle 10g. I have all users and passwords.

Can someone help me?

Thank you in advance. Best Regards
