>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Extensions
>    Affects Versions: 0.7.1, 1.1.1
>         Environment: On Windows, NIO2's Files.move operation may not allow atomic file replacement, in which case it would have to fall back to the existing method.

> A PutFile configured with the "replace" conflict resolution strategy will first delete any existing file and then move the new temporary file into place. This causes there to be a small period of time where the file does not exist at all. This could cause problems with other processes relying on this file to always exist.
