You've probably experienced some disappointment after downloading a large file from an FTP server. The reasons of your discontent could be the following:
the downloaded audio-or video files turned out to be of inadequate quality or were just uninteresting to you;
the files from ZIP or RAR archives were not those you needed;
there wasn't the necessary person in the downloaded photo of JPEG format, etc.
The SmartFTPPlayer software will help you to assess files before downloading them :
you can view the bitrate for MP3 audio files and the names of the performers, albums, compositions, genres, etc.;
you can view the encoding characteristics of video and audio tracks for AVI video files and also view separate film frames;
using the built-in player, you can listen to audio files or view video files in most of the popular formats, and MP3 and AVI video files can be listened to or viewed from any position, not just from the very beginning;
you can download not only the whole AVI video file, but also selected parts, for example, a separate scene from a film or the performance of your favourite actor from a concert;
you can view JPEG photos while downloading and it's possible to stop viewing them at any moment;
you can view the contents of ZIP or RAR archives and download any file from archives;
you can open any file from FTP servers even if the files are in ZIP or RAR archives.
