Hi, it doesn't set it because it cannot. All 3rd party applications that use Dropbox use their REST API, and their API doesn't allow it. The Dropbox client on Windows can set it because they use an internal API that others cannot use:

Other cloud providers do the same thing, e.g. the OneDrive REST API will not allow uploads over 100MB in size but their own client can.
