#### Notes

- An ftp client is a program that you use to transfer files between computers using the ftp protocol. The UNIX command-line program ftp is a text-based ftp client. (This client is also available on Windows and Macintosh OS X. ) FTP clients that offer a graphical user interface are available for most platforms. Instructions on how to use the command-line version of ftp that is available for Windows, Unix, Linux, and Macintosh OS X can be found at http://www.tldp.org/HOWTO/FTP.html.
- Downloading through a Web browser is usually easier than using an ftp client. Try clicking the link for the file you want in the table above. Most modern browsers handle ftp downloads correctly. If you get no response or an error message, see Troubleshooting before trying to use ftp directly.

- Be sure that your ftp program is set up to do binary transfers, not text transfers.

- If you are in an organization with a firewall, you may want to try setting your ftp client to passive mode (ask your network administrator).

- Instructions for configuring your browser for passive ftp mode:
- - For Internet Explorer: http://support.microsoft.com/?kbid=309816
    http://support.microsoft.com/?kbid=323446
    Internet Explorer 6.0 sometimes has problems with passive ftp; see:
    http://support.microsoft.com/?kbid=816037
  - Instructions for MacOS 9: http://docs.info.apple.com/article.html?artnum=31283.
  - Instructions for OS X: http://docs.info.apple.com/article.html?artnum=151794
    http://docs.info.apple.com/article.html?artnum=61422
    When you're looking at the Proxies tab, check the checkbox Use Passive FTP Mode (PASV).
  - For other platforms: You can usually find the control for passive ftp in the browser's Preferences... or Options... dialog. Ask your system or network administrator if you need help.

- Click here to see a sample session with a command-line ftp client on UNIX. User input is shown in `boldface.` Note the use of the bin and passive commands.
- Not all ftp clients or browsers provide passive mode.

- Some ftp clients fail to show all of the files in the NCBI ftp directory. If you can't find the file you're looking for, get the file from the most recent subdirectory of the ftp directory sequin/old.

- NCBI does not currently offer secure transfers with sftp.
