But that would be deleting the rest of the data in the table. I dont want to delete that data.
Just the 450M of data that I loaded previously.
And that too seems to be deleted as it wont show that particular data if I do a select statement.
But the hard drive still shows the same amount of space being occupied as it was when I loaded the 450M data file.

Also if I decide to delete the data file, how can I do that?
Thanks.
