Help for home folders and sharing connections

Good morning, i hope that some guru here can help me, because after a lot of search i was not able to find a solution. I have a READYNAS 102 OS 6.4.2, FlexyRaid Nas has 1 user, XXX Nas has 3 shared folder, call them AAA,BBB,CCC. With SMB, folders have read/write for admin, read only for XXX, and no other permission. 1° problem When i MAP network folders in windows, no problem, because winidow ask me for a path (IP\Share). But i have found that exploring the NAS with other applications, example is X-PLORE android, i can connect the NAS even without any logonid nor password. Of course AAA, BBB, CCC are not accessible, but i can connect and see my shared structure. Is there a way to avoid this? I'd like that the NAS ask me for user/passward ALWAYS if no anonymous access is allowed. This could be a security problem. 2° problem I do not want home folder, so, how can i disable this feature? Or, if this is not possible, how can i prevent user XXX to write in his Home/XXX folder? In Shares/Shares i cannot see any "home folder", so i can set any permissions In Shares/Browse, i can see all the subfolders, and io have the possibility so access options, BUT HOME icon is not like the other folders, and on it i have only the option to browse (with no effect) and nothing else. Hope someone can help, Regards, Luciano
