When submitting an assignment in Canvas using the "File Upload" tab, you might receive the error message "Attached files must be greater than 0 bytes." This error indicates the submitted file cannot be accepted by Canvas. This could mean the submitted file is corrupted, or that it is not the file you intended to submit.
If you received the "Attached files must be greater than 0 bytes" error, try opening the file to make sure it works. The file could be corrupted or broken. If the file won't open, try downloading it again, and then opening it again to ensure it downloaded successfully.
Troubleshooting summary:
- Try opening the file to make sure it is not corrupted
- If the file won't open, download it again
- Try opening the new file, if it opens, submit it
