How does AVFS cache?

AVFS uses file level caching. The caching technology called Dual Path is build-in in the AVFS file system. On playback a file is either coming from the cache or coming from the spindles. Or a complete file can be copied or ingested to the cache and duplicated to the spindles. If no longer in the cache the file is taken from the spindles. Caching, cache mode and direction are selectable per directory/folder.
