Ideal place to cleanup root cache directory in cefsimple

[linuxcef07]

I am running cefsimple app from branch 120 (6099) on windows.
To address CEF process crashes, I am checking return value of CefInitialize() and also using unique root_cache_path value based on the process ID.
Now, cache is getting created in respective root cache directory based on unique root_cache_path.

Now, I am looking for way to cleanup these cache data once respective process work is done. I can cleanup cache data in invoking application but I am looking for proper place in cefsimple itself.
Initially, I thought of cleaning cache data before CefShutdown() in cefsimple_win.cc but sub-processess will not come to that code path.
Can someone please share the ideal place/function to cleanup cache data by each sub-process in windows?
Do I need to implement/override any method for this cleanup?

I think cache should be set up before CefInitialize and cleaned up after CefShutdown. That, I think, excludes any CEF object methods.

Thanks @ndesktop for your reply.
I am setting up unique root_cache_path for each process before CefInitialize(). It creates 4 cache directories (i believe one per subprocess) in my parent cache directory during rendering.
Is it safe to delete parent cache directory (which includes cache directories of all subprocesses) after CefShutdown() in cefsimple_win.cc?

I did not implement this scenario. I am doing the cache initialization only in the browser process.

Thanks @ndesktop for your reply.
Does anyone know the ideal cleanup place/function if I am creating unique cache directory for all processes in one parent directory?
Thanks in advance.

You should only configure cache path for the main process. You can then clean up the path after CefShutdown.

Thanks @magreenblatt for your reply.
I need to set unique value for CefSettings.root_cache_path as well to fix CEF issues at my end for branch 120 onward (as mentioned in https://github.com/chromiumembedded/cef/issues/3615 and https://github.com/chromiumembedded/cef/commit/a25f89f9e4a5b702de4f0e4726cfee2f4f94426b)

Also, I can see that cefsimple is still locking cache files even after CefShutdown() for long time. Because of this, my cleanup code is not working even after CefShutdown().
I found a reference which also talks about the same- https://magpcss.org/ceforum/viewtopic.php?f=6&t=18686

So I am cleaning up the cache in my application (which invokes cefsimple). Thanks

I optimize cache folders after CefShutdown in the main process. It works for me.
