File format

When you attempt to upload a file to an assignment in the Add a File window, you may see an “Invalid file type” message.  The file does not upload in the window.

  • Check if the assignment submission page has an “allowed file extension” section.  If so, your instructor has restricted the assignment to the specific file extension type.
  • Is there a special ASCII character such as  / \ : * ? " < > | & # {}  in the file name?  Problems may arise if file names contain any of those special characters.  Rename the file to remove the special characters then upload the file.  
  • How long is the file name? Rename the file and keep the name under 45 characters.
  • Are there any leading or trailing spaces in the file name?  Remove any spaces at the start or end of the file name. Otherwise, spaces in file names are allowed, but you may wish to use underscores ( _ ) instead.
  • Are there one or two periods before the file extension (for example ..doc)? There should be only one. All file names must have a valid extension. It is good practice to only use periods in a file name between the file name and the extension. In particular, avoid using two consecutive periods ( .. ) in a file name. Two or more consecutive periods may cause problems, such as a broken link.

File Size

The maximum file size that can be uploaded in D2L Brightspace is 2GB per file.  The 2 GB limit is hard-coded into all areas of D2L Brightspace, except for tools with smaller size limits (such as the Locker tool).

For 2 GB or larger files, the file may begin to upload but stop at a percentage (e.g. 50% or even 100%) in the assignment.  However, a message may eventually display with the "Oops. File could not be uploaded" message and the file will fail to upload to the screen. 

In these cases, try to make the file smaller or break it up into multiple files.

Internet Connection

Files are uploaded in D2L in 10MB chunks and times out if a 10MB chunk takes longer than 2 minutes to upload.  It may appear that your file is continuing to upload after the two minutes, however it is not.  It the file upload timeouts, you may see an "Oops - File could not be uploaded" message in the Add a File window.

In this case, check your Internet connection to make sure the computer is connected to the Internet and try again.
