Why has Windows taken so much space on my drive?

Hi TH

Issue: I just erased and prepared a 60GB Vertex 3 SSD for windows installation.
I plan to use the drive for Windows 7, Sony Vegas Pro 11, Cubase 5, and a few tiny apps like quicktime.
I have other HDD for data storage.
I did a fresh installation of windows 7 and after checking the drive I only have 20GB of free space left. :heink:
Any idea why windows used so much space? Did I install it incorrectly?

Thanks, Greg

  1. If you don't use hibernation, go into the power settings and disable hibernation. This will remove the hiberfil.sys file which is usually the same size as the amount of ram you have installed. If you have 8 gig of ram, the hiberfil.sys will be 8 gig. i'm not sure where the rest of your space is.

    Windirstat can help track down large files.

    I actually have 16GB of ram. So I can effectively remove 16GB of un-needed files?
    Sounds good. How do I get into power settings and disable hibernation as you say?

    you can delete rather than disable hyberfil.sys

    Go to Start menu, type “cmd” open up command prompt
    Type “powercfg.exe -h off” [make sure you are an Administrator]
    ENTER
    Type “exit”
    ENTER

    restart pc

    also with 16gb of ram you will have a huge pagefile --drop that to 1gb

    also turn off or lower the size of system restore

    you can also cleanup service pack one install files--dont do this if you ever want to uninstall service pack 1

    open cmd prompt same as above and type

    dism /online /cleanup-image /spsuperseded

    and press enter

    Also, as an alternative to windirstat there's SpaceSniffer (free download, I'm too lazy to get the link).

    You can also use the mklink /J command from command line to move over some files to your big drive...

    OK I removed hibernation with command. Gained 12gb straight off.
    Going good. You already helped a bunch. How do I drop the page file?
  8. Go to control panel>system and security>system
    Click on advanced tab
    In the performance section click on settings
    Again click on Advanced > click on Change in the Virtual Memory section
    choose custom size--Change the virtual memory [pagefile size]
    restart your computer

    it is possible to set 0 pagefile but there are a few programs that may not like it--though i have mine at 0 and

    have had no problems--but 1gb is probably fine

    One thing not mentioned here, turn off System Restore = more space saved
  10. i did mention

    "also turn off or lower the size of system restore "
  11. You can set a limit to your shadow copy storage, and after doing a bunch of installs and stuff, your $TOPS file may be pretty big. Instructions on how to do both are at http://nerdsknowbest.blogspot.com/2013/01/phantom-space-used-in-windows-7-windows.html

    Wouldn't suggest disabling it though since it comes in handy when problems come up after installing a new program or windows update - better to just limit it's size !
