Ok, so I try opening Photoshop and I get this:

I pressed OK and then this popped up:

Photoshop shutted itself off and I assume that "scratch disk" means HDD. So I checked my space:

I have a 120gb HDD. So I am so confused. I should have about 8gb free.

MFT also takes up space.

And MFT is...?

MFT = Master File Table

Here's Wiki's NTFS entry

http://en.wikipedia.org/wiki/NTFS

And what is that?

Man, I feel like such a noob.

.:EDIT:.
And besides that how does my computer that has 120GB Suddenly have about 200GB?

Read Wiki's NTFS entry. MFT is explained there

I still don't understand how assumingly "80gb" is not enough space for PS to run if it can run at 4gb and under.

You say 80 GB, but I only see 80 MB of free space.

Have you cleaned the hdd of temps and redundant files? The hdd tends to clog up with all sorts of junk after some time, especially after surfing. Also, 111 GB isn't all that much ;) I know. If you have lots of audio and movies, 111 GB is next to nothing.

<div class='quotetop'>QUOTE(Mighty Midget @ May 29 2007, 09:40 PM) [snapback]291907[/snapback]</div>Yes I know. I have a lot of video and music and games. :whistling:

But last night I had like 8gb. And when I went to open PS then I checked at it cannot be that low. I am clearing temp dirs now.

Meh, I've got 450 GB and been running low already lately.

I have 1GB now. But that's still too low. D:

Gosh, I still got my Pc that's not that up to date anymore and only 40GB of hard disk space, but I never run low on that, there's always enough eventhough I have quite a few games on it and some movie files.
First of all, to get some free space you could disable the System Recovery in your System Control. That's maybe not such a safe option, but I found I never had any use of that thing and no problems without it whatsoever, unless of course you aren't careful enough with files on your hard disk. Besides, without it you already should have quite a lot of space freed.
Also you should go to the folder c:\Documents and Settings (something like that), there to every folder of each user, there to the folder Local Settings\Temp and there delete everything since it's just temporary files and take up unnecessary space.

I have no virus scanner or anything so I don't think I should disable that. ;D

Done that already.

Have you defragmented the hdd lately? I believe that sometimes a messy hdd can report wrong capacity.

Hehe. I haven't EVER defragmented in my whole time of using a PC.

oh dear......

If you get a virus, System Restore won't help you none. I say you should delete all restore points sans the most recent one. This should save you some more HDD space.

And, of course, DEFRAG IT NOW!!!
If you don't bother much about defragging, use this. It's a time-limited trial, but PerfectDisk is probably the best defragger I know of.

also if sectors are badly damaged it shows the wrong numbers. it used to be scan disk but now it's back to check disk to repair the errors.

'Horseman is right, if you get a virus the normal consequence would be that Windows would stop working, system restore including. Still I use system restore all the time even though I've never had problems, everytime I try some software and don't want to keep it, instead of just uninstalling I do a full system restore so as the registry doesn't get clogged with leftovers.

Defragment and stuff but IMO it's just impossible to account exactly for hard disk space nowadays. You just have to leave some margin. Virtual memory also has discspace allocated. Do you use P2P? Once eMule alone took around over 30 Gb with temporal storage of redundant downloads --that is "let's download the same thing from five sources in case the first option's file is invalid, so as to save time since I've got bandwidth to spare". :P
