| Applying the crushftp.server.root and crushftp.user.root JVM runtime parameters at least , will have the equivalent results of UNIX chrooting. |

| Before applying the restrictive run time arguments, the __TempAccounts__ and __Preview__ folders need to be moved under the path set for user root. The server __SSL keystore__ file to be moved under the server root. Then the settings updated accordingly.\\ |
| Especially in case of setting the __Dcrushftp.server.file.strict__ flag to __true__, for in case of any kind of misconfiguration in this area, the server process will not start.\\ |
