FileZilla Client and FileZilla Server?

What is the difference between FileZilla Client and FileZilla Server?

I’m using windows vista ultimate 32bit. What was written on the filezilla page is that FileZilla Client is for all platforms and FileZilla Server is for windows only.

But there is not much information.

Please advise on what is best and thank you in advance for all your thoughts and views.

FileZilla Server is an FTP server that clients can connect to. You provide access to some portion of your hard drives for download, upload, or both by other users.

FileZilla Client is an FTP client for connecting to an FTP server someone else is running.
