The Content Collection is the area in which you can store documents, attachments, media, etc. on Blackboard for current and future use. Once you add material to the Content Collection, you can add that material to a content area by using the Build Content menu.
From the Course Content page, you can upload single files and packages. Instructions on uploading file and packages are available on How to Upload Files to the Content Collection.
To better organize your course, you can create folders for files and packages.
Select if you want to overwrite the file with the same name, and then click Submit.
If you want to replace an existing file in a folder, like a course syllabus that you have updated, this would be a good item to overwrite. Otherwise, your students may be confused on which syllabus (or other content) they should be viewing.
The files will be nested with the folder you selected.
