Change the size of the cached file set

Suppose I set the size of the cached file to 256M before, then I cached about 200M files, and then I changed the size of the cached file to 0M. Excuse me, "Will the 200M I cached before be deleted?"

The issue contains only a cache-size scenario and asks whether previously cached files are deleted; it names no file, test, or entry point. First locate the cache-size configuration and its existing tests, then confirm the behavior and document or change it once the expected outcome is decided.
