Accelerates file transfer by multithreading: it opens several ftp connections to a host, while a connection waits for an answer, the other connection may transfer data; this accelerates the download, upload, or synchronization of websites. The visitors of a website see the old pages while the new page is uploaded, when the upload is complete the page is renamed. You can start a synchronization out of the windows explorer: you find an entry in the right click menue to upload/download a file or directory. You can exclude filetypes or directories from synchronization (or confine it to certain filetypes/directories only). Further you can automate the processing of logfiles (or any other host generated data file): at preset times it can download files, decompress each file, and then it issues a command to process the decompressed file.
