File upload control

• The maximum file size that you can upload is 2GB. You can change the file size, in the Web.config file. See Change the size limit for uploaded files.
• When running in an on-premise multi-tenant or Azure environment, you can only upload files to the store; you cannot provide a file path.

The File upload control is not context aware. During a capture activity, you cannot add documents to the current folder using the File upload control, as the folder is locked.
