 ### -MinimumFileAgeDays
-Specifies a number of days.
-The deduplication engine optimizes files that users have not accessed in the number of days that you specify.
-If the last access time is not available, then the deduplication engine uses the last modified time.
+Number of days after the file is created before the file is considered to be in-policy for optimization.
+
+The **Default** and **HyperV** usage types set this value to 3 to maximize performance on hot or recently created files. You may want to modify this if you want Data Deduplication to be more aggressive or if you do not care about the extra latency associated with deduplication.
