Hard drive free space missing

Win 7 - 64 bit

I have Ben having problems over the last 24 hrs with viruses, partly my own fault. These have now been resolved. But for some reason the free space on my c: drive has gone from just under 20gb to just under 10gb causing a red bar to appear.

I've not installed anything, certainly nothing like that sort of size file. I have checked the folders on the c: drive but cannot see anything obvious that could be robbing all this space.

Any help would be appreciated. Thank you

Thanks for the link.

I found one area called 'Page File'that was taking up allot of space. In fact I did do a bit of research and disabled it and found I gained 15gb!!of hard drive space back. But not knowing if this is something I should be doing I re- enabled 'Page File'again even though I saw not affect on performance anywhere, not even when using FSX.

I would be grateful if someone could tell me if it is ok to leave 'Page File'permanently disabled or not. Thank you.

I forgot mention. Prior to changing page file I did carry out a defrag which clawed back 5gb of space but still left me with a 4gb short fall.

The page file is a windows one that is used by Windows as extra memory when it is temporarily needed. It was absolutely necessary in older computers but as you already have 16GB of true memory and running a 64 bit version of Windows it will probably get on fine without it

You can also set the size and location of the pagefile (swapfile) in Control Panel\System\Advanced System Settings\Advanced\Performance Setting Advanced Button\Advanced\Virtual Memory. Delete the settings (most likely "let Windows control my Swapfile" and set it up for a specific size on whatever drive you use least. Don't forget to reboot and recheck it has changed

Use something like CCleaner to remove all unwanted files

Here is a quick explanation of CCleaner's features.


Using the Cleaner window (the default window when you launch CCleaner), you'll notice several checked boxes that indicate which areas of your computer will be cleaned. Most of the boxes are checked by default, so pay close attention if you only want to scrub certain areas. Tabs at the top offer the ability to clean Windows areas and other applications. Switching between the two tabs allows you to make your choices for a customized cleaning.

When you're done with your settings, click the Analyze button on the lower left to see which items will be cleaned. You'll see every file CCleaner will delete and also exactly how much memory will be returned to your system after the cleaning.

Note: It pays to peruse this list before hitting the Run Cleaner button to make sure you're not deleting something important. When you're ready, hit Run Cleaner and watch CCleaner go to work.


Click the Registry button on the left side of the interface to bring up another set of checked boxes. This set of tasks does everything from eliminating unused file extensions to trashing obsolete software. Uncheck the boxes you don't want to scan and click the Scan for Issues button. At the end of the scan you'll be given the option to click the Fix Selected Issues button. Recommend tick all except Run at start up.

Note: It is highly recommend you save your current Registry configuration at the prompt in case of a malfunction later. An additional window will ask if you wish to fix specific items. If you know of a specific item in the list that is not a problem, simply tell CCleaner not to fix it by unticking the box. Remember, if you save your configuration beforehand a mistake here is easily reversible.


Uninstall - Windows comes with its own Add or Remove Programs utility, but it's often slow to load and not the easiest Control Panel item to configure. CCleaner quickly lists all of your active programs, and lets you highlight and uninstall software you no longer want. This part of the program utilizes tools already included in Windows, but the convenience and speed for quick uninstallations is tough to beat.

Startup manager - To manage your start-up programs, click the Startup button under the Uninstall button in the upper left of the interface. You'll see a list of active start-up items that launch when you boot up your system. Be very careful here: some items are not immediately identifiable and you wouldn't want to shut down your firewall, antivirus program, or any other important program.

System Restore - This will show you all the restore points on your machine (they can take up a lot of space), the latest one is greyed out so you cannot remove it . To remove any or all of the others just highlight the restore point listed and click on the Remove button.

Drive Wiper - Here you have the option to "erase" an entire drive or just the freespace on a drive. What happens is CCleaner overwrites the drive / space with zeros making the data unrecoverable. In the security box you have the option to select how many time CCleaner will write over the space / drive, 1 is sufficient for normal use, 3 will stop data recovery programs from finding anything, 7 is secure from anyone expect CSI and 35 is just paranoid.

Note the bigger the drive / larger number of passes the longer it will take.


Settings - Allows you to set language and other options. Run at startup will wipe your temp files and user history eveytime you log on.

Cookies - Lists cookies to be deleted if you want to keep certain cookies because they hold log in details for your favourte sites then just highlight the cookie and click the right arrow key to move into the right hand column.

Include - Allows you to add folders, that are not in CCleaners default list, that you need deleteing everytime CCleaner runs.

Exclude - Allows you to add folders that may be in the default list that you do not want CCleaner to remove.

Advanced - Lets you select / deselect options advanced users may decide to untick things like warning messages and backup prompts.

Once you've run through the entire cleaning process, don't be surprised if your computer runs a bit faster.

Depending on the capacity of your hard drive, you'll also free up a shocking amount of space if you haven't run a program like CCleaner recently.

Thank you for your reply and info.

I already use CCleaner. I think one mistake I made was not backing up my registry. A lesson learned.

However, I've now sorted things out an am pretty much back to normal.
