How can I check the default location where PL/SQL saves files?

By default, in PL/SQL, the location where files are saved is defined by the `UTL_FILE_DIR` parameter. You can view and change the value of this parameter by following these steps:

1. Log in to the PL/SQL database as a system administrator.

Run the following command to check the current value of the `UTL_FILE_DIR` parameter:

   SHOW PARAMETER UTL_FILE_DIR;

This will display the currently set file save path.

If you need to modify the value of `UTL_FILE_DIR`, you can use the following statement:

   ALTER SYSTEM SET UTL_FILE_DIR = '<new_directory_path>' SCOPE=SPFILE;

`` is the directory path where you want to set as the new file save path.

Restart the database instance to apply the changes.

   SHUTDOWN IMMEDIATE;
   STARTUP;

This will restart the database and apply the new parameter settings.

Please be aware that changing the `UTL_FILE_DIR` parameter may involve security and permission issues. Proceed with caution and make sure to only allow authorized users to access and write to that directory.
