How do I view TRTC logs?

TRTC logs are compressed and encrypted by default with the XLOG extension. You can set setLogCompressEnabled to specify whether to encrypt logs. If a log filename contains C (compressed), the log is compressed and encrypted; if it contains R (raw), the log is in plaintext.
