An efficient charged particle identification (PID) is desired in almost all particle physics experiments. In particular, for a flavor-factory experiment such as Belle II, the PID information is absolutely essential. The Time-Of-Propagation (TOP) counter is a novel ring-imaging Cherenkov detector that primarily consists of a quartz bar radiator with micro-channel plate photomultipliers. These TOP counters are installed in the central region of the Belle II detector to provide crucial information on PID. We present an overview of PID studies in Belle II, with a focus on the performance of the TOP subdetector. The results presented are from the most recent data recorded.
