GUIDE: Basic tips to save disk space in Windows 7

post #1 of 27
Thread Starter 
The Dreaded G Man's recommended Windows 7 disk space savers

SSDs are often much smaller then HDDs so saving disk space can be quite helpful so you can pack those programs and games onto it.

Disable System Protection:
Most SSDs are fairly small compared to HDDs so making a complete system backup is not difficult.
Disabling System Restore will save you several GB of disk space, and saves time when installing new stuff since no restore points are created.
If you use System Restore regularly, or can't live without it, do not make this change.

Step by step:
Control Panel\\System and Security\\System
Click System protection link on left
Choose C: drive from list
Click Configure...
Click Delete
Choose Turn off system protection radio button

Click OK until dialogs all closed.


Disable or shrink hibernation
If you don't use hibernation mode, disabling it will save you several GB of disk space.
If you do use hibernation mode, you can still shrink the hibernation file size.

Step by step:
Disable hibernation completely:
Type cmd in start search menu
Right click cmd.exe (Command Prompt) and choose Run as administrator
Type: powercfg.exe -H OFF and press enter


Reduce Hibernation file size to the minimum (50% of RAM size):
Type cmd in start search menu
Right click cmd.exe (Command Prompt) and choose Run as administrator
Type: powercfg.exe -H -Size 50 and press enter


Reduce page file size:
Quite a few of us here on Overclock.net will have 4GiB or more of memory.
This is enough that your page file doesn't need to be very large (for most people!)

Step by step:
Control Panel\\System and Security\\System
Click Advanced system settings link
Click the Settings... button in the Performance section
Click the Advanced tab
Click the Change... button in the Virtual memory section
Un-check Automatically manage paging file size for all drives
Choose the C: drive from the list
Click the Custom size: radio button
Enter a small value like 250 or so in the Initial size (MB): field
Enter a larger value like 1000 or so in the Maximum size (MB): field
Click the Set button

Click OK until all dialogs are closed, a restart will probably be required

There are countless other things to reduce or move to other places, and I wrote a guide before on moving your media folders, but this is meant to be a basic guide so it will only contain these 3 items for now.

Looks like a great guide, although obviously more helpful to others than to me.

Would reducing the paging file size still be alright on hard drives? I've managed to fill up my Samsung drive (the one which Windows 7, my programs, and downloads are on)

All of these changes would apply as well to a HDD.

Mainly they are more useful on a SSD because of the limited space available but I would still size my page file to match actual usage, and since I never use more then 5 GB of RAM at once, then max 1000 MB page file is enough for me.

I can't remember the last time my page file was even used. I'm installing Ubuntu in VMware Workstation at the moment along with a few Windows programs and it's using around 3.64GB.

Hmm, there was some other SSD guide somewhere which told me to get rid of pagefile all together. Now I don't know what to do.

Well, if you never need more than your 6GB of RAM then you could get rid of it. If you run a load of stuff that requires a lot of RAM and often find yourself using a PF, don't get rid of it

If you don't know how much RAM you're using, you can use something like Process Explorer's "System Information" window which has a peak commit figure that's tracked, keep it running in the background and try to consume as much memory as you ever would (run a bunch of large programs) and see what your peak figure was.

Subtract your physical memory from the peak figure (assuming the peak is larger then your RAM) and the remainder is the max size your page file should ever reach... add a few hundred megs for safety and boom there's your page file size

There is alot of controversy about what to do with the pagefile.sys

I will probably will look more into it.

Thanks for the guide!

Tom's Hardware says if you have 8GB it should be fine for the most part to disable the swapfile/pagefile, but don't be surprised if some programs don't work. Some people have had the swapfile/pagefile disabled and have never had any problems though. So it's up to you.
