+    This looks for files that pass the filtering response
+    The filtering system uses key-value pairs
+    The key is double encoded using a '-'. The first part is the ID of the item to filter,
+    the second is the method:
+        min - Minimum Inclusive
+        max - Maximum Inclusive
+        exclude-# - exclude, followed by a number to uniquely add, (will create a triple [], ignore the third as random)
