When to Use?
If your course is running low on space but the items in the course's Content Collection are needed and in use, you can compress the images in a file. This is specifically for PowerPoint (pptx) files.
Procedure
- Open the original PowerPoint file in the Microsoft Office PowerPoint application
- Once open, select File > Compress Pictures
- A box similar to this should display:

- Change the "Picture Quality" to your liking (Suggest using On-Screen)

- Select OK
- Save the file (File > Save As) again with a new name
- This file should now be smaller than the original one
** Please note that when re-attaching the newly reduced size files to your Blackboard course and their content items, you will need to delete the original sized file from the Content Collection **
- Navigate back to your Blackboard course where you would like this file placed
- Once in the course, go to the Course Management section
- Within that section go to Content Collection > click on the Course ID of the current course that you are working in

- Locate the original uploaded file from this list and Delete it. Doing so will remove the original file and allow you a little more course quota
- Navigate back to the content area/item that this original file was once placed
- With the original file deleted, you will receive an error such as this one when looking at the content area/item:

- Click on the drop-down button next to the title and select Edit
- Scroll through the settings until you get to the Attachments section
- Within that section, you will see the error again about an Invalid File
- Click on Mark for removal (this will change it to Unmark for removal)

- This will remove the Invalid File from the content item
- In the Attach Files box, select Browse Local Files
- Navigating through your documents until you find the newly reduced size file that we compressed and saved earlier
- Once located and selected click on Open or OK
- The newly reduced size file has now been attached to this content item
- Click Submit in the bottom right-hand corner to save your changes
- You should now see the newly reduced size file attached to the content item
- Repeat steps as needed
