Thanks for the answer.
1. Do you have a link to SlimFTP Server please?
2. Will I also could run SlimFTP on Windows 7 64-bit?
If I search via Google, I can find a program developed in 2006.
you can use slimftp and its free. it uses a script file like apache2 does and is very easy to setup. i run it myself. you could install the apache2triad and it includes slimftp as well as http, sql, and pyphon.
