The program works by first scanning a selected site and producing a list of all files linked from that site. You may then select the files you want to download and they will then be saved on your system.
Since scanning is a much faster process than downloading, this process is quite efficient and in most cases is quicker than simply downloading everything from the site, especially in cases where you only want a small portion of the site contents.
In addition to selecting files to download from the result of a scan, the program also allows you to download any specific list of files, which can be from any number of sites.
This list can be created manually or imported from a text file. Since the scan results can be exported to a text file that can later be imported, this enables you to scan and download at different times, or to download additional files from the same site without having to scan it again.
