Asterisk recording place changing/formatting

i have new asterisk 11 version and my recordings are stored in

i want it as old such as ==>/var/spool/asterisk/monitor

wt do i need to modify in the dial plan ?

i googled and found in /etc/extentions_additional.conf

wt should i modify it ?

that example that you found it is for FreePBX. You need to edit the file /etc/asterisk/asterisk.conf

astspooldir => /var/spool/asterisk
astspooldir is where all records are stored. When you have a voicemail message for example you can find it in /var/spool/asterisk/voicemail/, when you record calls with the Monitor command the files will be stored in /var/spool/asterisk/monitor and when you record a conference call the record is stored in the directory /var/spool/asterisk/meetme.

Also you can specify a custom path directly on the app doing the recording example MixMonitor()
