Nice. You answer with a question.
And you fail to answer. Guess you are not really looking for help?
You expect from me to answer to my question ?:D
If you know if it's safe or not to delete this file, answer ( if you want ) but if you don't know, do not answer, do not ask why / when / who / what
:)
Cheers

And why should I not do those things? It is stated in the rules I must only answer your initial question with no question of my own?

And why would you delete it?
Nice. You answer with a question.

Well we would like to know why you want to delete this file that only takes up 824 bytes.

But hey why not just DELETE the whole System32 folder. That way you won't have all those extra files on you PC.

No, we expect to understand your reasoning on asking the question that you asked, since it is a very odd question.

Ok guys. I'll try to explain why do i want to delete this file
Some sites ( advertising, i guess ) are blocked in this file, manually. After i made this changes, i have some problems with "login" on some forums. Sounds wired, but it is so.
I don't know if it's allowed to say which sites i blocked, but some online newspapers are very very slow because of this sites. I'm not sure if it's advertisings, but anyway, they "block" some online newspapers.
I use Mozilla Firefox as default browser, but i tried Google Chrome / Opera / PaleMoon, and is the same story.
:)

This is what the file should look like.


# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost


Just copy and paste it into your hosts file opened in notepad. Save as all files with no extension.

Just for information sake, you have to open Notepad as an Administrator to be able to edit the Hosts file, I don't believe there has to be anything 'in' the Hosts file but I would not delete the file.

I would be very surprised if the system still worked after the hosts file would be deleted.

I would be very surprised if the system still worked after the hosts file would be deleted.

More then likely it would do 1 of 2 things.
1) Recreate that file.
2) Do nothing and not worry about it.

That file is there for the user to make changes to block or redirect certain IP addresses (at your choosing and discretion), whether local or public (internet). If it isn't there I don't think it would matter to the OS. As it is now it does not contain any info except on how configure/edit it, note the # in front of every line.

Why not just try it. Rename hosts to hosts.old. Reboot and try to go online. If it fixes your problem, great, if not, rename hosts.old to hosts and reboot.
