DiskFileItemFactory | The default `FileItemFactory` implementation.

## Package org.apache.tomcat.util.http.fileupload.disk Description

A disk-based implementation of the `FileItem` interface. This implementation retains smaller items in memory, while writing larger ones to disk. The threshold between these two is configurable, as is the location of files that are written to disk.

In typical usage, an instance of `DiskFileItemFactory` would be created, configured, and then passed to a `FileUpload` implementation such as `ServletFileUpload`.

The following code fragment demonstrates this usage.

            DiskFileItemFactory factory = new DiskFileItemFactory();
            // maximum size that will be stored in memory
            factory.setSizeThreshold(4096);
            // the location for saving data that is larger than getSizeThreshold()
            factory.setRepository(new File("/tmp"));

            ServletFileUpload upload = new ServletFileUpload(factory);

Please see the FileUpload User Guide for further details and examples of how to use this package.
