OBS v29.0.0 is the minimum supported version now to use the obs_frontend_get_last_recording and obs_frontend_get_last_replay functions introduced in v29 to grab the recording/replay filename direct from OBS instead of checking with the host filesystem. Overall this simplifies much of the filename/renaming code.
Sub-folders are now supported
Recording folder setting option now removed and no longer needed to be input by the user
