   - **handleExe** - Populate this field in order to allow RenameFile plugin to close all open file handles.
     - In Windows, a file can't be renamed if the file is opened by another process. In other words, if a file is being played by Stash or any other video player, the RenameFile plugin will get an access denied error when trying to rename the file.
     - As a workaround, the 'handleExe' field can be populated with the full path to handle.exe or handle64.exe. (See requirements for download link)
