could a dump file without the extension .dmp??? I have trouble with one of the file that was sent to me from the client and the file only have exp_test_dmp without .dmp. I did a test on my machine and even I didn't specify with .dmp, Oracle still automatically had .dmp once the export is completed.
the question is the file exp_test_dmp without .dmp is a good file???
thanks and have a great weekend.
