it is quite easy to open server, just download xampp lite, install, open XAMPP setup then XAMMP start and tada, u got ur own server on ur ip.
how its working?
to access file -> netip/file.end
to add file -> paste the file in the HTDOCS folder
to delete file -> delete the file from the HTDOCS folder
if u want a domain name -> enter
www.no-ip.info, open account, download the program, add new host on the site with ur account (dont change stuff that u dont understand) now u can access files by entering WhateverNameUChoseForNoIp.NO-ip.InFo (unless u changed it when u made the host).
dont forget, every time ur ip change (like after restarting internet) launch the program and change the ips using ur account on it (the same one as the one in the site).
