You can resume any stopped downloading. If a file to be transferred already exists in the local directory and it is smaller than the one that is about to be downloaded, you can resume the downloading. When resume downloading a folder, Xftp checks the size of each file within the folder and selectively downloads the required files.

To append to the local exiting file:

1. Select the file in the Remote Folder window, and click Download.
2. In the File Exists dialog box, select Resume.
