[salt-users] download of a zip+ file from aws s3 bucket is corrupt.

I have tried using the s3.get and finally ended up enabling s3fs file
server back end on the Salt master.

Both the attempts ended with the file being downloaded/ copied on the local
file system without an error, but is unusable when trying to read/extract
it.

sls with s3.get :

  module.run:
    - name: s3.get
    - bucket: "test"
    - path: "manifest_installers/3.0.0/V11/test_win.zip+"
    - local_file: "D:\\test_win.zip+"
    - return_bin: "True"

sls using s3fs :

cp.get_file:
   - path: salt://manifest_installers/3.0.0/V11/test_win.zip+
   - dest: "D:\\test_win.zip+"

Checking the file contents from the master cache yields nothing :

(salt)-bash-4.1$ gzip -l
var/cache/salt/master/s3cache/manifest_installers/tscl/manifest_installers/3.0.0/V11/test_win.zip\
