How to copy files from your local drive to your personal web page at UHD
  1. Use WS_FTP to open two windows: Local System (your PC) and Remote Site (UHD Linux server).
  2. Locate the file(s) on your local drive that you want to transfer.
  3. Change the Remote Site path to the public_html folder by double-clicking on its icon.
    • Note: If you don’t see the public_html folder, follow the steps under the “How to Login to Linux using Putty” section.
  4. Select the file(s) you want to transfer. Choose the appropriate transfer mode:
    • ASCII: For .htm, .html, or .txt files.
    • Binary: For most other file types (.jpg, .gif, .pdf, etc.).
    • Auto: WS_FTP automatically determines the correct mode.
  5. Click the right arrow to transfer the file(s). Once the transfer is complete, close the WS_FTP session.

To view your files on the web, open a browser and go to: http://gator.uhd.edu/~username/, replacing username with your actual username.
