Question about freeing up D drive space
“This may be a stupid question, but I don't know much about computers, so I have to at least ask about it. I just happened to noticed my D drive was 2.29 GB free of 18.1 GB. This computer is only 3 months old, a HP desktop with Windows 7 factory installed. I have no idea why there is so little space left here, and I'm not aware of putting anything on the D drive. Can someone tell me how to free up space on D drive Windows 7? Any advice and information on this is appreciated?” –from Windows ten forums
Main symptoms when D drive is full
Although the capacity/size of hard drives keep growing at an incredible pace, we still find ways to make them easily become full. Before your D drive is getting full and leaves no space for new data, you will notice the following two obvious symptoms.
> Low Disk Space alert – If the free space of D drive reaches 200MB threshold, there is a balloon Low Disk Space notification on bottom left with warning message.
> Red bar in File Explorer – When the free space of a drive is less than 2GB, you will find the default blue bar of the drive turns into red in File Explorer.
6 quick ways to free up space on D drive in Windows 10/8/7
Next, we will show you how to free up space on D drive in Windows 7/8/10 for your new applications or files. So, without further ado, let’s get started....
1. Disable Hibernation
Hibernate is a neat feature to save the content of your computer’s memory to the hard disk, which can make your computer start fast. It is allocated at almost 100% space of your computer’s installed RAM. For example, if you have a 8GB of RAM, your hiberfil.sys file will take up 8 GB of your hard drive space; if your RAM is with 20GB, your hiberfil.sys will occupy 20 GB.
Generally, Hibernate is enabled by default without hurting your computer. Therefore, if your D drive is almost full and every gigabyte is important for you, you can disable Hibernate to free disk space using the following steps.
(1) Click the Start button and type “cmd”.
(2) Right click the item that appears and select “Run as administrator”
(3) In the opened DOS command prompt window type “powercfg.exe /hibernate off”and press Enter
Then the hibernate.sys file that is used by the hibernation process will be deleted and you will free up space on disk equal to the size of your RAM.
2. Perform a Disk Cleanup regularly
Windows comes with many great tools to help keep your computer's storage nice and tidy. Disk Cleanup is the first and foremost one. It allows you to delete the temporary files and some other unnecessary data, sometimes the size of those files can amount to several GB. So performing a Disk Cleanup regularly is a great way to free up disk space in windows 7/8/10.
To perform the Disk Cleanup function:
(1) Click “My Computer” to open File Explorer.
(2) Right-click the D drive and select “Properties”.
(3) Under the “General” tab, click “Disk Cleanup”.
(4) Windows will scan your drive and calculate how much space you can save by running Disk Cleanup.
(5) Select the files that you wish to delete form the drive, and hit “OK”.
To free more space, you can use “Clean up system files”. With this function you can remove older Windows restore points from your drive, leaving only the most recent one.
3. Empty the Recycle Bin
As we all known, when you delete items like files, documents, videos from the computer, they don’t get deleted immediately. Instead, they are stored in the Recycle Bin and continue to take up some valuable space of the drive. So you can empty the Recycle Bin to completely/permanently delete the unnecessary items.
To empty the Recycle Bin:
Go to your desktop, right-click on the “Recycle Bin” and click “Empty Recycle Bin”. You will see a warning pop-up asking whether you are sure you want to permanently delete your Recycle Bin items. Click “Yes” to proceed.
This could free up some space on your disk.
4. Turn off System Restore
System Restore is able to back up of the important system files in order to make it convenient to restore the system in time when something goes wrong. But this method is not quite effective. It is better to use a free cloning software to make a system backup. The System Restore service usually take up a lot of disk space, so here's how to turn it off:
(1) Right-click “Computer” and then click “Properties”.
(2) In the left pane click “System Protection”.
(3) Select the disk you want to turn off System Protection for and click “Configure”.
(4) Select “Turn off system protection”, click OK, and then click OK again
5. Uninstall programs you do not use
For most computer users, most the D drive space is taken up by all kinds of applications. If you don’t need some certain programs, you can uninstall them to free up disk space in Windows.
Again, Windows provides the utility to help you easily remove any unwanted programs on computers. To uninstall/remove programs, follow the steps below:
(1) Click “Start” --> “Control Panel’ --> Uninstall a program under “Program”.
(2) A list of program will appear, now you can see how much space is occupied by every program.
(3) Right-click any program that you wish to remove, and click “Uninstall”.
6. Transfer data to external storage drive and then format/wipe the D drive
The 5 methods listed above mainly focus on how to delete or remove files/programs from hard disk. However, what if you want to free up the D drive, but don’t want to lose all the data on it? Like the precious photos, videos and musics, and other media types which can accumulate to some serious storage space. So how to get rid of such dilemma?
