Here is what the manual states on p. 13:
Using The FTP Server
NASLite-2 exports all storage disks to the local
network via FTP (File Transfer Protocol). NASLite-2
will name all installed and configured fixed disk
drives available on the server computer as Disk-0
through Disk-N in consecutive order where N will be
based on the total number of installed disks. These
names are fixed and cannot be changed. All Disk-N
folders are accessible by all users. NASLite-2 also
exports three additional folders as follows:
Typical NASLite-2 FTP Shared Folders
1. Shares Exports all available storage
volumes via a single share.
2. Remote Exports all remotely hosted
storage volumes.
3. Status Exports NASLite-2 status
information pages.
You will be able to connect to the NASLite-2 server
via any FTP client. For example if your NASLite-2
server IP address is set to 192.168.1.251, entering
ftp://192.168.1.251 in the Windows Explorers
address bar will access the server contents. Here
files and folders may be dragged-and-dropped to
and from the NASLite-2 server window.
