Filepicker
Filepicker widget allows the user to drag and drop files or upload files by browsing the filesystem and selecting one or more files in a directory.
File types must be a valid MIME type according to input element specification or a valid file extension.
To accept any/all file type(s), set Accept file types to an empty value.
MIME type determination is not reliable across platforms. CSV files, for example, are reported as text/plain under macOS but as application/vnd.ms-excel under Windows.
