How can delete preference files?
How can avoid this warning?

Thanks in advance

What exactly is the warning message?

Hi Marco

The message is in logon process (warning):
You have preferencesets with the same definition, this might not work correct.

Regards
Pedro Gutierrez

You get this message because you appear to have preference sets with the same rule which makes it difficult for PL/SQL Developer to determine which preference set to use.

If you go to Tools > Preferences and click the Preference sets button [..] you get the dialog where you can check this. If you find two preference sets with an identical "connections" setting. You need to change this, either by deleting one, or by defining a different connection setting.
