First, thanks for reply.
My windows is corrupted due to this I am unable to start oracle software. But data is available in e:\drive. If my windows is available and oracle software, I can able to export and import. But there is new windows installed and new oracle is installed. Then my question arises. How to export my e: drive data i.e., in windows folders like oradata, ora81 folders into the newly created empty data folders in my d:\ drive. Please solve my problem. Please try to understand my problem. Thanks in advance.
