How do students put something in the dropbox

From D2L Wiki

To Submit one or more files to a dropbox in your D2L course, students should follow these instructions:

1. Select Dropbox from the navigation bar. This brings up the list of available dropbox folders (assignments).
2. Select the link for the appropriate dropbox.
3. Select Add a File to select a file from your computer. In the popup window, select Browse to find the file. Select Add to upload more than one file. When finished select Upload in the lower right.
4. Enter any Comments to your instructor.
5. Select Upload in the lower right.
6. A confirmation page appears indicating which file has been uploaded.

Additional Notes

• To find out at any time what files you have ever submitted, select the linked number in the Submissions column. If you haven't uploaded any files, it is an unlinked 0.
• You cannot, as a student, delete a file you have submitted.
• If you submit a file with the same name as an existing file you previously submitted to the dropbox, the new file will be renamed: for example, "JamesReport.doc" to "JamesReport(1).doc". The previously submitted file will not be overwritten. Your instructor will see all them, along with the date and time they were submitted.
• Use the Cancel button, as necessary, to avoid submitting the wrong file.
