D2L: Dropbox

Printable Version

If your instructor has the Dropbox tool available in a course, you may turn in digital assignments and be assigned grades through the dropbox. You will receive an email confirmation for each dropbox you submit.

Best Practices

The following are the best practices for naming files to ensure they can be opened by your instructor:

  • File names may contain alpha characters A-Z or a-z, numbers 0-9, underscores, and hyphens.
  • File names should not contain spaces. Use hyphens or underscores in place of spaces.
  • File names should not contain special characters: * / : ; > < ’ & # { } ” other than hyphens and underscores.
  • Files names should only contain one period (.) and that period should be located between the text name you assign to the file and the file extension (e.g., pdf, doc, docx, xls, xlsx) assigned by the application used to create the file.

There is no limit to the size of the file you submit to any dropbox folder. However, uploading large files to a dropbox may be affected by the speed of your internet connection and the browser used.
