Blackboard: Quota Tips and Tricks

 

 

NOTE: Due to the large size of Audio, Video and narrated PowerPoint files, it is no recommended these files be uploaded directly to Blackboard. Instead, they should be uploaded to Chipcast (Panopto) or YouTube and the link shared in the course shell to provide access to the content.  The following article outlines this process: Upload / Share Existing Media.


Course Quota Overview

Each course on the Blackboard system has a quota limit of 1 GB. This is generally enough space to accommodate a semester's worth of content, however, you may need to adjust this and only upload a week's worth of material at a time. Courses exceeding the limit will display a notice near the top of the Blackboard window when attempting to upload additional course content.

 

NOTE: Additional course content cannot be added until the course is brought below the quota limit. Please note that removing content from the course does not reduce the quota unless the corresponding file is removed from the Course Files area as well.

Managing Files to Reduce Sizes

  • Before uploading large PDF files to the course, use Adobe's online file compression tool to reduce the size:

  • Powerpoint presentations containing multiple photos or graphics should be compressed to prevent unnecessarily large file sizes, refer to the following section for more information.


Reducing the File Size of a Picture in Microsoft Office

Linked here is the Microsoft's walk-through on Reduce the file size of a picture in Microsoft Office.

Use PowerPoint's built-in image file compression feature to quickly reduce the size of all images in your presentation. Right-click on the image and select Under Picture Tools, on the Format tab, in the Adjust group, click Compress Pictures.


 
  • When inserting photos in a presentation or document, try to use the .jpg format to obtain the smallest size possible. Most image formats can be converted to .jpg using basic photo editing programs, such as Microsoft Paint and iPhoto. Photos saved in .jpg may show some quality loss, however, the file sizes are typically much more manageable than other file formats.
     
  • All videos, such as recorded lectures, YouTube clips, and the like, should be placed on a separate streaming server (i.e. CMU's Chipcast / Panopto) and linked to within Blackboard. Contact the Help Desk to receive assistance from the Media Production team.
     
  • If uploading a recorded audio clip, always use the .mp3 format rather than older formats such as: .wav, .aiff, or others.
     
  • If creating PDFs using Adobe Acrobat, consider converting the document to grayscale. Grayscale PDFs are typically 50% smaller than color PDFs.
     
  • If creating color PDFs using Adobe Acrobat, consider using RGB color versus CMYK. CMYK color uses an additional data channel that creates larger file sizes in comparison to RGB color documents.

 

Consider the Use of OneDrive to Store Unused Course Files

If you have course content that you would like to preserve for later, but may not be actively using in your course now, you may consider the use of Microsoft OneDrive to help reduce course shell quota allocation used. Storage space is allocated to all students, faculty, and staff by default, so this option is available to everyone.
