I tried to upload my assignment submission file to a D2L dropbox, but it said "Oops, you file couldn't be uploaded."  What do I do now?

Examples: galvezessay2.docx, turnerwork4.docx, albahrainfinal.docx, or mkg4april.docx.

D2L's dropbox system doesn't accept many special keyboard characters.  Depending on the computer or device you are using it might not accept spaces, either.  While many IT systems do accept these (and they're a great idea for strong passwords!) many systems still do not.  So name your files with letters or numbers, and keep them under about eighteen characters long (before the extension, such as .docx.)  

Microsoft Word will suggest using some characters from the first line of your file, and may add special characters.  Instead of accepting that, choose a better name according to the simple guidelines above.  

And don't change the file extension (.docx).

My Professor won't accept my chosen file format. 

You may like using .pages or Google Docs, or perhaps prefer to save your finished work as .pdf.  And for your own purposes, that's great.  But Microsoft Word's format, .docx, is a universal business standard.  If your professor insists that you submit work in that format, she or he is doing you a favor: preparing you for the professional worlds of business, government, education and healthcare where this is an (often unspoken) expectation.  Luckily, Apple's Pages, Google Docs, and various other word processors allow you to save in .docx format.  

I try uploading a file but D2L says "Invalid file type"
