I believe I have uninstalled the oracle 9i. After that I tried to delete the direcotry "oracli", however it turned out I could delete everything in this directory except "oracli\10.2.0\BIN\oci.dll". It always pops up a window showing "can't delete oci.dll -- Access denied. please make sure disk is not full or write-protection..."
The disk is NOT full. I also found the interesting thing --- I tried to unset the "read-only" property for this file and its upper folders but everytime after I was done and re-check the property, I found it was set back to 'read only" again. No idea why.
Anybody cna tell me why this file can't be removed ? And how to remove it ?
