Securely Delete Pagefile.sys And Hiberfil.sys?
Dec 28, 2011
I run Windows 7-64 bit Home Premium and work on encrypted containers with TrueCrypt. I'm afraid that such sensitive information (including passwords) may be unencrypted on pagefile.sys or hiberfile.sys. How can I securely delete both of these files? I know there's a method in Windows 7 to delete pagefile.sys at shutdown but I heard from different sources on the net, this is unreliable and does not in fact SECURELY delete the content inside pagefile.sys.

The files pagefile.sys and hiberfil.sys are 8GB and 6GB accordingly. Are they important? Can I delete them or at least reduce them?

I have two drives, C and D. D used to be an OS drive in another computer, and I just use it now as a 2nd drive to store some extra stuff. So yes, the Prog Files folder is there, the Windows folder is there....
Anyway, is it possible to somehow delete hiberfil.sys off of the D drive? That is, without physically removing the drive, and using it in an enclosure.

I had an additional Windows installation for testing purposes, on a different partition and now I want to delete everything associated with it because I need some free space.
Although I managed to take ownership and delete the Windows folder and few others, I can't delete System Volume Information and the pagefile.sys file.
System Volume Information - I can't get "ownership" of the files in the directory. Although I'm listed as an "owner" of the directory with "full control", when I check "Replace owner on subcontainer and objectes" I get "Access is denied" and then "Stopping propagation of the owner leads to an inconsistent state..." I think I came across this before, but I have no idea what to do. I also get "access denied" when I try to change the read-only attribute of the directory.
pagefile.sys - when I right click on it, the security tab says "The requested security information is wither unavailable or can't be displayed"
note: I can't format the partition

Recently someone hacked my gmail account, I normally use "Lastpass" for save password, but now i think its not secure. Is it OK if i put my passwords into text files (encrypted) and save it my PC. Because if i forget them i can't use my emails ad FB accounts. Is it ok if i save passwords using web browser password manager? But i have Xmarks and Firefox sync.

I'm running Windows 7 x64 with a Quad Core and 4GB of RAM. I've enabled Readyboost on two USB devices of 2GB each I had laying around: a SanDisk Cruzer Micro, random read speed is 5341 KB/sec, random write speed is 3068 KB/sec. And a Kingston FCR-HS219, random read speed is 3412 KB/sec, random write speed is 3739 KB/sec. Not much, but should suffice to give it a try.
While booting, I saw and improvement. But the thing is I have my computer on 24/7 so I don't care that much about boot time. And I don't see a lot of activity of these devices once is turned on. Specially over the pendrive.
Is it because I have > 2GB RAM? Or is it because they are too small?
Would I benefit if I create a pagefile over one of these devices instead of Readyboost?
How can I "measure" this?
Is there a guide regarding Readyboost and USB devices?

I heard that the pagefile uses a lot of space on the ssd and they were right, I reduced it to 800-900mb on my C drive and kept it at system managed on secondary drive. What is the recommended minimum page file size? I have win 7 ultimate x64, 16 gigs ram and my C drive is a 240 GB Kingston HyperX 3k

I don't fully understand how all this works yet, and I'm not sure if I can disable this and still expect it to run smoothly! Some places I looked said that with anything over 4gb of ram, I really wouldn't need it, but others said keep it for sure..

I was wondering what's a good size for a Windows 7 pagefile partition? I have Windows 7 installed on my primary drive (OS) and decided to make a 7GB pagefile partition on my secondary drive as I heard it is better to have the pagefile on a different hard drive. I have 6GB of memory installed if it makes any difference.
Is 7GB enough? I noticed the partition already gets filled up so I had to disable that annoying "hard drive disk space is low" balloon notifications that kept popping up.. people are getting away with having no pagefile so I figured 7GB would be more than enough?
I should add that I am not experiencing any blue screens of death or any problems despite the notifications popping up.

Ok so I was trying to install dell quickset which doesn't work no matter what I do since I upgraded to 8gb or ram and installed a ssd. The main problem is I don't have the pagefile turned on so windows won't boot and safe mode boots but only has 240MB of ram and it so full you can't run anything.I have no system restore points. All I need to do is undo the max memory setting. Tried last known config, running msconfig in safe mode, bcdedit.

I have 64-bit Windows 7 running on drive C.
w/ Readyboost enabled (if this matters)
Is it possible / feasible to move my pagefile to my 32-bit (D) drive?
I googled but couldn't find an answer.

Ever since I changed my RAM modules, Windows always allocated more space to the pagefile. When I had 4GB of RAM, the advised size of the pagefile by Windows was 6GB. I now have 8GB of RAM and Windows recommended size for the PF is 12GB. So I set a fixed size of 12GB for the PF and didn't let Windows manage the file by itself. I'm about to get 4x 4GB of RAM for a total of 16GB. And I think it would be really exaggerated to allocate 16GBx1.5=24GB for the pagefile, especially because my system is on a 60GB SSD.
I want to keep a pagefile so please don't advise me to disable it. This is my workstation and believe me I will use all of the 16GB of RAM. My question is: what is the size I should give to the pagefile to avoid any problem (like app crashes)? Is there a way to see in Windows how much MB or GB is currently used by the pagefile? --> That would be a good way to assess my needs.

how much ram I would need to buy to turn off the windows virtual memory? And should I buy ECC or non registered memory? Would 8 gigs of dual channel memory be enough? Also,is it ago to have to sets of dual channel memory (4 x 2 gigs DDR3-1600mhz)?

My biggest folders are seemingly Network Service and AppData. My OS is on an SSD with 60GB, I have another 1TB SATA and a second 60GB SSD as well. If I were to create these two folders in the second SSD, and make them point there, would this cause any issues? I am trying to re-enable my pagefile because it is currently set to 16MB and I can't create a full memory dump unless I set it back to the original 8GB. I only have 4GB free on my SSD, and it is not enough. The other SSD is empty and entirely available.

I bought a PC with a quad-core system with 16Gb RAM, a 128Gb SSD C: drive and a fast 1Tb D: drive. I just discovered that I have an 18Gb C:pagefile.sys and started wondering about the pros and cons of having this paging file on my SSD C: drive. Given that I have 16Gb RAM, I could probably get away with no page file at all. I could certainly manage with the pagefile entirely on the "traditional" D: drive. Are there any guidelines on pagefile placement in the SSD era?

In my first partition I have windows xp, and in the second partition windows 7.Is it safe to use only one swap / pagefile from only one partition (first one where resides windows xp)?My pagefile size is set to be in the first partition and at fixed size (minimum 4096 Mb maximum 4096 mb).Or should I make/move/user a swap file from the second partition (windows 7 partition). Far as I know from my benchmarks the hardisk is faster in the first partition (first 20 GB), that would be the xp partition, fast in the second one (from 20 to 50 gb) after this the speed is decreasing.I am using windows xp because Photoshop and some games seem's to be far more resposive and faster than in windows 7, and I use windows 7 for internet related & other stuff

I'm trying to optimize performace of my SSDs.Can I move Pagefile, TEMP and TMP files to my Ramdisk? I already moved interenet cache.I have 32GB of memory available and an 8GB ramdisk. Memory allocated to ramdisk is dynamically managed by software (Primo Ramdisk Ultimate) so only the used portion is used and not the full 8GB.

How can I stop Windows from swapping the VirtualBox application's memory to disk when it's idle? It's a performance issue when my guest OS looks for data and it's not available - also since it makes use of its own sawp partition.

I recently had a problem with reformatting a partition. It was solved by relocating the pagefile.sys.
Now whenever I boot upon login it says the system has made a temp pagefile system. I try adjusting the size of the pagefile system to much more, less, or equal to amount of ram (4gb). Doesn't seem to solve it.
dropbox has stopped working too; it seems like that malfunction may be related to the pagefilesys

As you can see the drives list is blank, and I cannot change the location and size of pagefile!
Does anyone have the same problem or have some tips to solve this?

I have a videoediting software that I am runing on 32 bit Windows 7 with 4 Gb RAM, the company that makes the software suggests to set the Virtual Memory/PageFile Size to double the RAM amount.I looked and mine is set to auto, I have many drives and all say none and are grayed out under paging file size for each drive. Which drive should I double the paging file ? the drive the software is installed on ? what about all my other drives, once I take it off auto they will not be managed. Should I set them all to double the RAM and if so how will it affect my system?

I'm using Corsair SSD as Windows 7 x64 boot drive, and I moved both User & System Variables TMP/TEMP directory to a new common TMP directory in another hdd (Drive D) & also disabled pagefile on my boot drive (but enabled it for Drive D).
Question is, what happens if I take off my hdd (Drive D and Windows 7 / applications need a temporary directory which doesn't exist anymore ? Will Windows 7 be smart enough to create a new temp dir in the original location ? I wonder if the dependancy on the hdd as TMP directory becomes critical.
About pagefile, I understand Windows 7 needs a min pagefile of 400MB on boot drive to allow memory dump. What happens if I disable pagefile on boot drive & enable it on another drive ? Will memory dump work ?

"Windows created a temporary paging file on your computerbecause of a problem that occurred with your paging file configuration when you started your computer. The total paging file size for all disk drives may be somewhat larger than the size you specified".

I have a system with 32gb DDR3-2400, a 256GB SSD and a couple of spinners. I have set up 4gb of the RAM to be used as another RAMdisk using the softperfect software. This problem has been going on for some time, but has been more of a problem since I started using the RAMdisk. Not because the RAMdisk itself isn't working well, because the stuff that is stored there keeps getting reset.I have pretty much identified that when updates are installed through windows update (either from Microsoft update or from my WSUS server), the following are reset to defaults
1. Pagefile is automatically managed and stored on the C: drive and is set to 32gb
2. The TEMP and TMP environment variables are reset to the C:users default location
3. The temporary Internet Files location is reset to the default C:users... location
There may be others that I have not discovered.I have manually set my swap file to 1024/2048 on the D: drive (a spinner), on the belief that it should rarely if ever be needed with a system equipped with 32GB of RAM. I'm certainly not inclined to waste 32GB of space on my SSD for an unused object.I have placed the TMP/TEMP files, cookies and Temporary Internet files on the RAMdisk to squeeze a little extra performance out of the system. (Yes, I know, I'm not really getting much benefit).Photoshop and a few other programs also use the RAMdisk as a scratch disk, and were the main reason I set it up in the first place.This is becoming a real pain when it gets reset as I have to manually change everything again. Anyone know a way to make windows leave settings at what I set them, instead of having it continually reset the values to what it wants? I'd prefer to have it my way. I know there will be proponents of "leave things as windows wants it".
