FlushCache deletes files from the FS local disk cache. It has no implact on Cedar 5 except in performance. (However, if the server which stores the file that you just flushed is down, you will be out of luck.)
It can be used:
a) to force a retrieval of a certain file when naext referenced.
b) to give advice to FS that a file or group of files will not be needed for a long time.
