OBS Studio
Every OBS Studio session writes timestamped text log files and performance profiler captures that record startup checks, plugin loading, encoder initialization, scene collection events, dropped frames, and render or output timing samples. These diagnostics accumulate under logs and profiler_data so users can troubleshoot crashes, streaming instability, and source performance over time; Kudu removes those old log files and profiler traces without touching scenes, profiles, recordings, service connections, or settings.
Why clean OBS Studio?
- Hundreds of accumulated session logs make it harder to spot the current startup or crash report, so users end up opening the wrong file while troubleshooting a black screen or failed stream
- Profiler captures from past rendering tests can consume noticeable disk space after repeated encoder, filter, or scene benchmarking, especially on systems used for frequent stream setup changes
- Old logs preserve repeated warnings from removed plugins or previous device setups, which can mislead users into chasing errors they no longer have when diagnosing audio or capture problems
- After GPU driver, encoder, or plugin updates, historical profiler timing data no longer reflects current performance, so comparing against stale traces can hide the real cause of frame drops and render lag
- Large log folders are often bundled into support uploads or zipped manually, making bug reports slower to prepare and harder for helpers to review because irrelevant sessions drown out the failing one
- Repeated profiler runs can leave behind many timing snapshots from test recordings and stream rehearsals, so users notice growing AppData or Application Support usage even though recordings are saved elsewhere
