FTP

Mount an FTP or FTPS server as a Windows drive.

Before you begin

Prepare the following in advance:

  • The FTP service must be enabled on the server:
    • Synology
    • QNAP
    • ASUSTOR
  • The server address and port (21 for ftp/explicit ftps by default).
  • A user account, unless the server allows anonymous access.

Connect

  1. Click Add in the toolbar.
  2. Choose NAS → FTP.
  3. Select ftp or ftps, and enter the server address and port.
  4. Optionally enter a path to mount a subfolder as the drive root.
  5. Enter the username and password, or tick Anonymous.
  6. Adjust Charset, Transfer Mode, and (for ftps) TLS/SSL if needed, then click Connect.

Settings

Setting Description Default
Protocol ftp or ftps (TLS) ftp
Address / Port Server host and port port 21
Path Server folder mounted as the drive root server root
Anonymous Connect without credentials off
Charset File-name encoding of the server UTF-8
Transfer Mode Passive or active data connections passive
TLS/SSL TLS version — ftps only auto
Read-only Blocks writes to the mounted drive off

Alternate address

Click the + next to Address to add a second line for a backup server address. The path stays the same as the primary address. If RaiDrive cannot connect with the primary address, it tries the alternate address automatically.

Behavior & limits

  • Plain ftp sends credentials unencrypted — use ftps (or SFTP) on any untrusted network.
  • FTP has no partial-write support; files are transferred whole. Editing very large files in place re-uploads them on save.
  • Wrong charset shows garbled non-ASCII file names — pick the encoding the server actually uses (older NAS firmware is often EUC-KR / CP949 or Shift-JIS rather than UTF-8).

Troubleshooting

Symptom Cause Fix
Directory listing hangs Active mode blocked by NAT/firewall Use passive transfer mode
Korean/Japanese names garbled Charset mismatch Change the charset in the drive's Options
ftps connects then errors TLS version rejected by server Select the TLS/SSL version the server accepts
