Can I resume large file upload?

[saher332]

I have a large video file that 16 GB and I copied it to dropbox folder and Dropbox desktop app showing me the file is being synced but I waited for more than 14 hours and still the same, my internet upload speed is 100 mbps according to speedtest.net

Hey @techperson, it looks like the file upload has been stuck on your end, please correct me if I’m wrong in my assumption. If it’s not too much trouble for you, could you elaborate a bit on the steps you’ve already tried on your end to amend this behavior, so as to make sure I’m following-up with you correctly? Are you seeing any error messages by any chance? I’d appreciate a screenshot (omitting personal info) of what the message reads, as it would point us towards the best next steps; please include it in your next message if possible. 

Thanks in advance for the time you’re devoting to work on that with me & I'll be awaiting your next update & we’ll take it from there!
