Doubt in Milestone 3

The config_params_to_correct_file_permissions needs to have only the keys added ?
if so the keys need to be comma separated or on new lines.
OR
do we have to keep the keys along with the values we provided in the file.

Also do we include versions in incorrect_file_permission_versions that failed upload/download ?

You have to understand what happens when you transfer a file from client to server, which version changes the file Permission.
Also please go through the taskBoard to understand as to what has to be done.

The keys (config parameters) are sufficient. If there is only one key, you can put that. If there are more than one, keep them on different lines.
