Post upload control options
In some environments, the multi-file upload control does not perform well (for example, due to conflicts with the browser). To allow companies to control the user experience, there are now several settings.
Post upload control options
The “use legacy single upload form” option switches off multi-file upload completely and reverts to the single file upload control.
The other options allow administrators to disable specific parts of the multi-file upload control that may cause issues. The multi-file upload control attempts to use all of these technologies, but may get stuck on one that should work but fails for some reason in the environment (for example, Silverlight).
By disabling this option, the control switches to one of the other options.
