The default is 365 days FsMinimumFileCacheAge The minimum age at which cached files can be deleted This parameter is used in conjunction with the FsCacheThreshold parameter to determine when to delete cached files FsCleanUpCacheDuringIndexing This parameter activates vault cache cleaning, while FsCacheThreshold, FsMaximumFileCacheAge and FsMinimumFileCacheAge are controling its behaviour.  Expect, when this is enabled on a system that currently has a large number of files in the FileCache table, the first cycle will take a long time to complete.
