Replace an existing file in Cascade
Let's say there's a "scholarship-app.pdf" in Cascade and you want to replace it with an updated version of the same name. In Cascade, click on the old file, then click the Edit tab. Use the Browse button to choose and upload the new file from your computer. After uploading, click the Publish tab. Note, this works with any file in Cascade (.jpg, .pdf, .doc, etc) but NOT with entire web pages.
