DDA

Direct Disk Access, or DDA, is a more efficient way of handling downloads and uploads than through the browser, which is especially important with large files.

When uploading or downloading through the browser, the storage and memory requirements are multiplied. There's the copy on disk being uploaded from or downloaded to by the browser, and the copy in Freenet's internal files. With DDA, Freenet reads from or writes to the copy on disk directly.
