Additional features in LeechFTP include multithreading capabilities (which allow you to upload/download multiple files simultaneously -- even when on different servers), the ability to queue files for later transfer, SmartResume (automatically resumes interrupted file transfers), HTTP file downloading capabilities, bandwidth limiting options, and customizable sounds (play different sounds when connecting, downloading, uploading, URL snatching, or after a failed download).
A URL Snatch feature that automatically begins downloading any file copied into your clipboard (i.e. clipboard monitoring), traybar icon support, an automatic update feature, proxy/firewall support, basic file comparison capabilities, a timer feature, file and directory upload/downloading, and an integrated archive viewer for compressed ZIP and RAR archives round out LeechFTP's impressive set of features.
