Details
Whenever a file upload completes, the corresponding input variable is set to a dataframe. This dataframe contains one row for each selected file, and the following columns:
name- The filename provided by the web browser. This is
not the path to read to get at the actual data that was uploaded
(see
datapathcolumn). size- The size of the uploaded data, in bytes.
type- The MIME type reported by the browser (for example,
text/plain), or empty string if the browser didn't know. datapath- The path to a temp file that contains the data that was uploaded. This file may be deleted if the user performs another upload operation.
