Many friends like me, after going to windows 7 64bit, I found that the so-called 35GB theory is not enough, even if you do not install any program files in the C: disk, and also use what every day & ldquo 360 security guards & rdquo; with & ldquo; Jinshan Guardian "clean up the garbage, but C: disk is still less and less every day, and finally will be around the so-called 7GB! So what is happening behind this?
c disk only has 6.84GB left.
In fact, we now open the C: drive, and then open the hidden files and system protection files, you will find, then the hibernation file and the page file take up a lot of space, So what is the space occupied?
Under normal circumstances, if you use 2GB of memory, then the hibernation file takes up about 2GB, and the page file usage is about 3GB. If you use more memory, For example, a single root 4GB, composed of three channels 12GB, then win7 default use of the hibernation file reached 12GB, the page file reached 8GB, so your system uses 20GB.
Windows 7 Page File:
Some large software consumes a large amount of hard disk space as a buffer because of the large memory consumption. This part of the hard disk space is the page file created by the software. It can alleviate the pressure of the system to schedule memory and improve the running speed of the software. The optimal page file size is 1.5 times the default memory capacity, but this is undefined. If the memory reaches 12GB, then 1.5 times is 18GB, but in fact win 7 defaults to 8GB, amount ••• In fact, we can set the page file on other hard disks, but in fact, if the memory is large, you can not set the page file, but I think it is better to set it up.
windows 7 hiberfil.sys hibernate and hibernation files:
Hibernate is to let the computer sleep, save the memory data into the hard disk, that is, Window saves the data in the memory to the next file in the root directory of the system disk. In the hiberfil.sys file, the size of hiberfil.sys is the size of the memory. The next time you start it, read the data before hibernation from hiberfil.sys! It is very convenient to save power!
windows 7 sleep:
and windows 7 Sleep combines all the advantages of sleep and standby. Sleep is to let the computer sleep, remove the power of other accessories except the memory, the working state data is stored in the memory, when the computer is woken up, the computer can enter the working state before sleep at any time. . If you suddenly lose power, hiberfil.sys in the hard disk also saves the data mirror of the memory, so you can also recover from the hard disk, although the speed is slightly slower, but at least do not worry about data loss.
Of course, it is very simple to turn off the sleep state:
Enter: powercfg -h off
Enter to get it!
But I wrote so much to tell friends, don't just close the page file and sleep File, because this will affect the stability of the system!
The following is how the hard disk of the author is actually expanding the C disk. In fact, after reading a lot of articles on the Internet, I found that none of them made me satisfied. But I wrote this one, this is very simple, at least I found this method the easiest after trying a lot of methods!
1, compatibility is very good, can be done under windows 7, the author is In 64-bit windows7, so 32-bit windows 7 is definitely no problem!
2, the steps are simple, just need a few steps!
3, very safe, one of the most important features is that The expansion method is very safe. For the data, it is the old saying that "hard disk is valuable, the data is priceless", it’s very Reliable!
Okay, I suddenly found out that I am quite a "mother" Stop, I am afraid of me because “ ” The word has written 8 thousand words!
Ready:
The first thing is to download EASEUS Partition Manager Software! Rest assured that this is free! What? Acronis Disk Director Suite! Still forget!
Right-click on the D drive and shrink your D drive! Do you understand this?
Then see the picture below
Drag the hard drive capacity progress bar above, if you feel To the inaccuracy, or input the number, the capacity of the expansion is very accurate, but when you enter the number, sometimes you find that the input partition is useless, first determine the remaining D disk capacity! Also the remaining partition!
Click OK, you will see the following interface
Right-click on the C drive, and the same operation as the D drive above, I will not take this step!
C The disc progress bar can be merged by dragging it to the right!
Click OK!
The c drive has increased 10GB and it has become 45GB. Is it really successful now?
You can see that the C drive capacity is still 35GB, the D drive is also the original, this software is very safe, before we can confirm, we can feel free to
of course all If you have no problems, just confirm it!
The first warning! Don't be afraid, bravely confirm, warnings mean " is one or more operations that require a system reboot!"
< Br> The second warning, I did not cut the map, it restarted. Friends, be sure to "tick" & rdquo; Oh, the system will automatically restart! Don't panic, I have spent 15 minutes to expand 10GB!
The following is the details!
The interface after reboot 1, divided into 2 steps, but you must not restart or shut down! Remember 15 minutes!
Interface 2 after reboot<<>
Interface 3 after reboot<<>
After restarting the interface, the tool runs.
The first process is almost finished!
The second process is finished!
Whether, the system message is being updated. , calm!
yes, process successful! so, long wait, 15 minutes, you can have a cup of tea!
Perfect access to the system, C disk capacity expansion succeeded, turned into 45GB. Haha! The stone has landed!
