5. You are now connected to the University of Houston –Downtown’s Linux server and ready to copy files from your local drive to your personal web page UHD.

How to copy files from your local drive to your personal web page at UHD.

1. WS_FTP LE has two windows, Local System and Remote Site

2. First, locate the Local System path to the drive letter and folder on your PC that contains the file(s) you want to copy to your personal linux account.



For example, double click on [-c-] if your local C:\ drive contains the files you want to transfer (use the scrollbars if necessary). Note: You move up the directory structure on either window by double-clicking on the green up arrow, and down by double-clicking on the appropriate folder/file icon.

3. Change the Remote Site path to the "public_html" folder by double clicking on the icon. Your WS_FTP LE gator.uhd.edu session should now display /home/student/d/username/public_html in the Remote Site window, as shown in the image below. Important!!! If the public_html folder is not displayed follow steps 6 and 7 under the How to login to Linux using Putty section.

Note: You may create new folders (directories) on either your Local System or Remote Site by clicking on the "MkDir" button, then enter the name you wish to give the new directory (folder) and click OK. Folder names are case sensitive. Folder_Names should NOT contain spaces. Use dashes or underlines instead.

4. Select the file or files you want to transfer by clicking once on the file. 5. Select the appropriate FTP mode (ASCII, Binary, or Auto) before copying or

transferring files from the Local System to the Remote Site.

• ASCII - FTP mode for .htm, .html, or .txt file extensions • Binary - FTP mode for most other file extensions including .jpg, .gif, .pdf and

.doc • Auto - WS_FTP LE should automatically set the appropriate transfer mode



6. Click on the right arrow button to transfer the file(s). When you are finished transferring files, close the WS_FTP session by clicking the Close button on the bottom left side of the session window, then close the window.

7. To access the files you copied to your Linux account, open a web browser and enter the URL to your folder on the server. Example - "http://gator.uhd.edu/~username/", replacing username with your user name.

How to access Oracle SQL using your Linux account.
