Local file system access can be disabled with the ''NO_LOCAL_FSYS'' ''Options'' flag in the ''[FTP]'' section of the ''[[dir:ctrl]]/[[config:sbbs.ini]]'' file or by un-checking the "Local File System" checkbox in the [[monitor:sbbsctrl|Synchronet Control Panel]]->FTP->Configure dialog. | Local file system access is enabled by default.

| When local file system access is enabled, a user with sysop access can "mount" a local file system using the FTP ''CWD'' or ''XCWD'' commands to change to "local://<path>//" where //<path>// is the local file system directory to mount. An alternative method of mounting the local file system is to use the ''SMNT //<local-dir>//'' command. To re-mount (switch back to) the BBS file system, the ''SMNT bbs:'' command can be used or ''CWD''/''XCWD'' command with a path beginning with ''bbs:''. | When local file system access is enabled, a user with sysop access can "mount" a local file system using the FTP ''CWD'' or ''XCWD'' commands to change to "local://<path>//" where //<path>// is the local file system directory to mount.
