I needed to edit a file on my computer and I found this page very useful

How to Edit Hosts and other Windows Files That Require Administrator Privileges

So I thought I would share it.

I have 3 questions.

When I opened (/windows/system32/drivers/etc) I found the file called host that I wanted to edit. I also found hundreds upon hundreds of files that are called hostbackup with a date up to 3 years old.

1.Is there any reason to save all those backups or can I delete them?

Seems like they are taking up a bunch of space.

2. Any other place that win7 is eating up my hard drive space with junk like this that I could delete to clean up my hard drive?

3. Is there some type of a freeware program that will do this project for me?

Thanks in advance.
