check tool for operation definition files.
For more information about where the temporary directory for extended commands is created

2. Running Explorer or any other tool, share the temporary directory for extended commands that
is on the backup server.
3. Running Explorer or any other tool on the database server, assign the shared temporary directory
for extended commands that is on the backup server as a network drive. For now, assign it to
X: on the database server.
4. Set access permissions for the automatically generated temporary directory for extended commands
that is on the backup server, to make it accessible to users who are executing extended commands
from the database server to read or write to and from it.
