| In this limited mode, the __TempAccounts__ and __Preview__ folders need to be moved from the default CrushFTP folder location to a location within the user data root. Then correct the path settings on Preferences->Preview page "Previews Path", respectively on Server Admin->Shares page, "General Settings" menu "Location of temp account file system" field. Otherwise image/document preview thumbnails or shared files can not be retrieved. If also the __"server.file.strict"__ flag is set to __"true"__, the CrushFTP service won't even start up for it's in violation of it's own access rules.\\ |

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