Moving Pagefile.sys To Another Partition Affects System Performance
» I would like to free up some space on my c drive and am thinking to move the pagefile.sys to another partition on the same hard drive but i'm not sure if it will affect performance.I read some articles saying it will, some saying it won't.What's the truth??
Pagefile.sys file is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the OS, hardware etc.
Your pagefile is a system file and can be placed on other partitions/drives or more often other disks to increase performance, under certain circumstance. That purpose is not what you are doing this for so another partition on the same drive will be fine, if it is moved correctly. I would really suggest you remove other junk files with a program like ccleaner if you haven't already to free up some space, then uninstall a few unused programs. also, If you haven't already done so, you can check to see if you have a hibernate option in the (start)>>Shutdown>dropdown menu. if so then you can remove the hyberfil file in the same dir (root drive by default) as the one you moved. this file can be enormous, and can be removed, and later reestablished.
If you MUST move the pagefile (as you've already done, although I believe you merely copied it) then it can almost definitely be deleted from the second drive ONLY. To move your pagefile to another drive you need to follow a set of steps so windows knows where it is once WINDOWS moves it.

You will not make it worse and you will not have to install a 2nd hard drive. You can just partition your hard drive that you used for Win7 and move your pagefile then.

I saw a definite improvement in overall "snappiness" and defragging the main partition is easier and more efficient since it doesn't have to work AROUND the pagefile pieces anymore.
Also don't neglect the most overlooked new performance enhancement feature - ReadyBoost will let you use an 8GB flash drive for ReadyBoost now. You just have to format it exFAT, instead of FAT32. I threw an 8GB SDHC in my 4GB notebook's internal card reader and made it the ReadyBoost drive and it improved absolutely everything.
- YUNIOR SORIANO replied on January 17, 2013: » it is difficult to see how anything would be faster by making the HDD heads move away from the primary partition every time that they needed to access the pagefile. For this reason, a second HDD containg the pagefile is generally accepted as the best place to relocate a pagefile as a second set of heads can work the pagefile while the primary drive heads get on with the important stuff.
- DONNA JARRETT replied on January 17, 2013: » While having a 2nd hard drive with the pagefile might be even more useful, my objection is you your point that it will adversly affect a system and performance. Installing a 2nd Hard Drive may even increase the performance, but moving the pagefile away from the System Drive has helped. I have noticed files moving faster among my drives and i have noticed that access time is quicker when loading some programs.
My main objection is to say that it would hurt the system, not that installing a second hard drive would be the best course of action. I was merely trying to show that it can be done with a single drive and still be effective.
- YUNIOR SORIANO replied on January 18, 2013: » Smart move. RE. pagefile fragmentation: It can happen, but if you don't restrict the pagefile by locking it into a partition, and let the system manage it, pagefile fragments when emptied will disappear to the point where the pagefile is no longer fragmented without any user intervention.
