I need command which will open ban files and take "BanName" from all of it and than go to the account of banned user and set Banned to 0....

This is just for one player, and you need to type his ip....
new banFILE[128],ip[32];
format(banFILE, 128, "NooBotRP/Users/Bans/%s.ban", ip);
new banneduser = dini_Get(banFILE,"BanName"));
format(file, sizeof(file),"NooBotRP/Users/%s.ini", banneduser);
dini_IntSet(file, "Banned", 0);

Ban files are named by ip_address.ban
Ban file contains:
BannedBy=DraGoN
BanDate=19/7/2011 at 16:57:46
BanReason=Cheat
BanName=Jeremy_Hakwins
