# Class FileUpload

java.lang.Object
org.apache.tomcat.util.http.fileupload.FileUploadBase
org.apache.tomcat.util.http.fileupload.FileUpload

public class FileUpload extends FileUploadBase

High level API for processing file uploads.

This class handles multiple files per single HTML widget, sent using `multipart/mixed` encoding type, as specified by RFC 1867. Use `FileUploadBase.parseRequest(RequestContext)` to acquire a list of `FileItems` associated with a given HTML widget.

How the data for individual parts is stored is determined by the factory used to create them; a given part may be in memory, on disk, or somewhere else.
