To efficiently manage your converted media files, you need to clear your .cache folder on a regular basis to remove files that are no longer used, are outdated, or are problematic. You can choose to clear all converted media files from the cache or only the orphan files. 您可能会需要在以下情况下清除缓存：
在您已删除 Wwise 对象后 —— 转码媒体文件或落单文件不再有用，但仍与对象关联，除非您手动清除这些文件，否则这些文件会一直保留在缓存文件夹中。In this case, you might only want to clear these files.
针对某平台转换文件后可能导致质量降低——您可能希望删除该平台的已转换文件并重新进行转换。
多语言文件的最终版本已经提交 —— 您希望在缓存中仅保留新转码结果文件。
Only the converted media files in your .cache folder are deleted in this
operation. The Originals folder remains intact.
