po/mo path changing

Hi,

maybe this is a newbie question, but can somevody tell me what custom path in Advanmced tab should be? Cannot find exact answer here.

Most of my plugins have mo/po files at default locations:
/wp-content/plugins/PLUGIN-NAME/languages

generally, it’s ok, however, when I copied mo/po files for a specific plugin to:
/wp-content/languages/loco/plugins

what custom path should I enter at Advanced tab?

thanks in advance,
T
