When creating a task within a workflow, there is the ability to create preconditions on the task which must be satisfied in order for the task to execute.

One of the preconditions available is a CHECK FILE which can either be set to check if the file exists or if the file does not exist.
Does the "exists" choice  for the CHECK FILE precondition on a task within a workflow validate that the file is 'stable', and that is its file size is no longer changing?
The CHECK FILE exists condition will be satisfied even if the file is not stable.
