Please make sure you have not changed the names of the submission files from your bulk download. If the file names are changed, please rename them to match how they appeared in the download. With different file names, Canvas will not be able to recognize the files that should be replaced.
Files must be compressed as a ZIP file for upload. If you are not sure how to create a ZIP file, please contact your administrator or consult your computer's software manual.
For best results, please upload submission files in their original format. For instance, if you download a Word document as a .doc, do not convert the file to a .docx.

Note: Depending on your computer's operating system, your upload may include hidden files with a ._ prefix. Canvas will ignore these types of files, as well as any files that do not match the file name of any students' original submission.
