Log into cPanel.

On the home screen under the files section choose "File Manager".

Next, choose where you'd like to start in. For this example, we're going to use the Web Root option - which is the public_html folder. Since we're uploading to the public_html folder we do not need to navigate anywhere else.

Select "Upload" from the icons at the top.

Navigate to the file you want to upload on your local computer by selecting the "Choose File" button.

Select the file and click "Open". Once the file is finished uploading you can click on the link in the center of the screen to return to the folder you uploaded the file to.

Now, in a web browser, we can visit the file and verify it uploaded to the location correctly.

Extracting Files from an Archive

Log into your cPanel.

Locate the File Manager tool under the "Files" category.

Navigate to the folder which contains the compressed file you want to extract, and select it.

With the archive selected, click the Extract icon from the top Toolbar. Alternatively, you can right click on the selected files and click on Extract from the drop down menu as pictured below.
