Can I upload large files to Dropbox?
You can upload files through the desktop app or mobile apps, no matter their size.
Files uploaded to dropbox.com must be 50 GB or smaller.
All files uploaded to your Dropbox must be smaller than your storage space. For example, if your account has a storage quota of 2 GB, you can upload one 2 GB file or many files that add up to 2 GB. If you are over your storage quota, Dropbox will stop syncing.
Note: Files uploaded through the API must be 350GB or smaller.
