Loads of hard drive space missing

Specs: Windows 64, Intel/6GB
Hello, I seem to be missing a rather large amount of disk space on my hard drive. It's meant to start with 465 GB, and it says i've used much more than I have.

It says i have 64.4 GB left, but I know I haven't used that much. So I installed Treesize free, and it detects 286.3 GB used. This leaves roughly 115 GB unaccounted for. Really bad. Is there any way you guys can help me/give me steps to find out where it has gone?

I'd check in the computer management console for storage. See help and support if you can't find it in control panel. Here is tips at web page.

It should show the drive and if you have a partition or not. You may have a hidden one that takes up a lot of space too. Don't delete it, just see what is there.

Be sure you try windows too. It has clean up feature. Right click on C drive in explorer and follow down to clean up. Run it.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Also know that Windows uses a paging file (virtual memory) when you need more room in memory the system moves 'older' pieces of data to the paging file to 'expand' the available memory. This paging file is reserved space but may not have any files actually in them so it is not available even you cannot count the space it is using.
You also have an expandable area reserved for system restore files and that will increase until it reaches the preset size (usually 12% of the drive size).
If you need to both of these can be adjusted in size, but be careful not to hurt your performance by lowering your virtual memory too far, and avoid lowering the system restore below 8% or you may not have enough restore points available.

You have to be a little bit crazy to keep you from going insane.

In addition to the above, if you are using FAT32 file system, you will have lots of wasted slack space do to the large cluster size when using FAT32 on a drive that large.

Another point not mentioned above is that hidden system files do not show up when using default settings.

Finally, the recycle bin can hold lots of items. Empty it, or better yet, download and run Ccleaner Slim from the link below.
