DUPLICATE: https://issuetracker.unity3d.com/issues/occlusion-culling-system-creates-too-many-files-in-the-library-folder-and-never-deletes-them

Baking occlusion the old occlusion cache files are not removed.

1. Open scene "BugReporting".
2. Go to Window->Occlusion Culling.
3. Bake occlusion.
4. Go to (Project Folder)/Library/Occlusion, notice the files in folder.
5. In Occlusion Culling change "Smallest occluder" to 0.08.
6. Bake occlusion.
7. Go to (Project Folder)/Library/Occlusion, notice that old occlusion files still exist.

I noticed that occlusion can reuse same occlusion files that had same scene and same options (but it will never be if you always update your scene). And after some time
(Project Folder)/Library/Occlusion folder can be very stuffed.

    I've noted performance issues if you don't delete them: my hypothesis is that the old files are some how corrupting a clean occlusion bake.

    Current deletion takes hours, approximately 4.

    @JTOWN- what kind of script did you use? I'm having the same issue here- 500k files/thrashes :-/. I was about to move my project folder, but it would copy in 7 hours!! (Unity 5.5.1f1).

    I had over half a million files sitting in that folder... had to make a script to manually delete them whenever I baked occlusion.
