How do group access rights affect all associated accounts?

[admin]

If a group enables the 'File Read' access right, this only means that all associated accounts are allowed to enable 'File Read'. If an account doesn't enable 'File Read' then any users of that account will not be able to download files. If a group doesn't enable 'File Read', then any account which attempts to enable 'File Read' will be ignored and users of that account will still not be able to download files. Only if both the account and group enable 'File Read' will downloading be permitted.
