<P> The content of a user's home directory is protected by file system permissions, and by default is accessible to all authenticated users and administrators . Any other user that has been granted administrator privileges has authority to access any protected location on the filesystem including other users home directories . </P> <P> Separating user data from system - wide data avoids redundancy and makes backups of important files relatively simple . Furthermore, Trojan horses, viruses and worms running under the user's name and with their privileges will in most cases only be able to alter the files in the user's home directory, and perhaps some files belonging to workgroups the user is a part of, but not actual system files . </P> <Table> <Tr> <Th> Operating system </Th> <Th> Path </Th> <Th> Environment variable </Th> </Tr> <Tr> <Td> Microsoft Windows NT </Td> <Td> <root> \ WINNT \ Profiles \ <username> </Td> <Td>% HOME%% HOMEDRIVE%% HOMEPATH% </Td> </Tr> <Tr> <Td> Microsoft Windows 2000, XP and 2003 </Td> <Td> <root> \ Documents and Settings \ <username> </Td> </Tr> <Tr> <Td> Microsoft Windows Vista, 7, 8 and 10 </Td> <Td> <root> \ Users \ <username> </Td> </Tr> <Tr> <Td> Unix - based </Td> <Td> <root> / home / <username> </Td> <Td> $HOME </Td> </Tr> <Tr> <Td> Unix - derived </Td> <Td> / var / users / <username> / u01 / <username> / usr / <username> / user / <username> / users / <username> </Td> </Tr> <Tr> <Td> Mac OS X </Td> <Td> / Users / <username> </Td> </Tr> <Tr> <Td> SunOS / Solaris </Td> <Td> / export / home / <username> </Td> </Tr> <Tr> <Td> Linux / BSD (FHS) </Td> <Td> / home / <username> </Td> </Tr> <Tr> <Td> AT&T Unix (original version) </Td> <Td> <root> / usr / <username> </Td> </Tr> <Tr> <Td> Android </Td> <Td> / data / media / <userid> </Td> </Tr> </Table> <Tr> <Th> Operating system </Th> <Th> Path </Th> <Th> Environment variable </Th> </Tr>
