Does any file in an FTP server ends up in an HTTP server?

Does an FTP server have to reside in an HTTP server?

And i have read that there is a command in the FTP specs called (REST - Restart transfer from the specified point.)and take as an argument the byte from which the server will start sending the file.

Not related at all. You can have one without the other.

From RFC959:

RESTART (REST)

The argument field represents the server marker at which
file transfer is to be restarted. This command does not
cause file transfer but skips over the file to the specified
data checkpoint. This command shall be immediately followed
by the appropriate FTP service command which shall cause
file transfer to resume.

Then if you have and FTP server installed (Only FTP server )can i get a file from that server using an HTTP request?

I know that i cause a headache about this but my problem is that iam building a download manager and i need a gurantee that i should only care about http connections because any file no matter what server it resides on can be downloaded via an HTTP request?

Please someone gets me out of this.

If a server handles only FTP requests then by definition it doesn't handle other protocols.
