Adobe solved the z@ tmp files issue

Back in 2014 I posted about these z@ tmp files that are sometimes created by Adobe Acrobat (or Reader) in the temp Folder and cannot be deleted anymore afterwards because they are still in use (see post here).

Adobe finally solved the issue in Adobe Reader 11.0.14, released in January 2016. See the release notes here: http://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotes/11/11.0.14.html
