Disk Utility is a system utility for performing disk and disk volume-related tasks on the macOSoperating system by Apple Inc.

Functions[edit]

The functions currently supported by Disk Utility include:^[1]

• Creation, conversion, backup, compression, and encryption of logical volume images from a wide range of formats read by Disk Utility to .dmg or, for CD/DVD images, .cdr
• Mounting, unmounting and ejecting disk volumes (including both hard disks, removable media, and disk volume images)
• Enabling or disabling journaling
• Verifying a disk's integrity, and repairing it if the disk is damaged (this will work for both Mac compatible format partitions and for FAT32 partitions with Microsoft Windows installed)
• Erasing, formatting, partitioning,^[2] and cloning disks
• Secure deletion of free space or disk using a 'zero out' data, a 7-pass DOD 5220-22 M standard, or a 35-pass Gutmann algorithm
• Adding or changing partition table between Apple Partition Map, GUID Partition Table, and master boot record (MBR)
• Restoring volumes from Apple Software Restore (ASR) images
• Checking the S.M.A.R.T. status of a hard disk

Disk Utility functions may also be accessed from the macOS command line with the diskutil and hdiutil commands.^[3]

History[edit]

In the classic Mac OS, similar functionality to the verification features of Disk Utility could be found in the Disk First Aid application. Another application called Drive Setup was used for drive formatting and partitioning and the application Disk Copy was used for working with disk images.

Before Mac OS X Panther, the functionality of Disk Utility was spread across two applications: Disk Copy and Disk Utility. Disk Copy was used for creating and mounting disk image files whereas Disk Utility was used for formatting, partitioning, verifying, and repairing file structures. The ability to 'zero' all data (multi-pass formatting) on a disk was not added until Mac OS X 10.2.3.^[4] Further changes introduced in Mac OS X Tiger, specifically version 10.4.3, allowed Disk Utility to be used to verify the file structure of the current boot drive. Mac OS X Leopard added the ability to create, resize, and delete disk partitions without erasing them, a feature known as live partitioning. In OS X El Capitan, Disk Utility has a different user interface and lost the abilities to repair permissions due to obsolescence,^[5] create and manage disks formatted as RAID, burn discs, and multi-pass format internal solid-state drives and encrypted external drives.^[6]

To function properly, your computer’s hard drive needs enough space. If you create space on your hard drive, you clean up unused files and fragments of data. Your hard drive might even need to be replaced if it is not large enough to meet your needs. If you use a computer daily, you may notice that your hard drive space has disappeared and wonder, “what is using the space on our hard drive?” The installed programs or saved files in Windows Explorer may not always provide a clear indication of its use.

You can make it out with Windows’ help. You can make sure you have plenty of free disk space on your PC by using the dedicated settings menu in Windows 10. The space utilized on your device and the type of content downloaded will be shown. You can use Storage Sense to automatically delete temporary files, Recycle Bin items, and other items you might not need. Follow these steps to view your internal storage and free up space.

How to Free Up Disk Space

The lack of sufficient disk space can lead to problems when saving files and slowing down your device. The author will show you how to find out what’s taking up hard drive space, how to free up disk space, and how to make cleanup safer and more efficient by using a reputable cleanup program.

How to clear disk space in Windows and Mac

The simplest way to free up disk space on PCs and Macs is to empty the recycle bin, clean the disk, delete temporary files, uninstall applications, and use a hardware junkware removal cleanup tool.

The garbage generated by many programs can be overwhelming. This makes you forget what it felt like when you bought your computer. What happened to all the free space? The next section tells you how much disk space you have available at present.

You can clear space on your Mac by using the Storage Management feature. You can delete important data or files when you clean out your trash on your own. Is there a similar feature in Windows? The only way to optimize your computer’s performance is to know what files it needs and which are not necessary.

The Avast Cleanup tool removes bloatware, obsolete programs, and old registry entries for outdated programs, but it keeps what you need. Try Avast Cleanup to reduce the time it takes to boot and improve your computer’s performance.

How about manually deleting files on your PC? This guide will guide you through the process. The steps are as follows:

Empty the trash process of cleaning a hard drive typically begins and ends with emptying the trash.

You don’t delete a file when you right-click and choose Delete or when you drag it to the Trash on a Mac. The file can still be restored.

You can let your Recycle Bin or Trash pile up over time if you don’t have a routine that cleans it out regularly. The solution to how to increase disk space is as simple as deleting all the data.

1. The Trash on Mac or Recycle Bin on Windows is accessible by right-clicking.
2. To empty the recycling bin or trash, click Empty Trash.

There! we are done! Please check the Recycle Bin first before deleting it. You can return to the file’s original location by right-clicking it.

There may be a notice that you may be about to delete a file permanently if the file is a bigger one than your available space on your main hard drive. It will help if you read everything before you make a decision.

Searching for something and not finding it? As a starting point, we should consider the stuff your computer doesn’t need, so let’s tackle the stuff you’re not using at all.

1. Use Disk Cleanup

There are many automated ways of deleting things from Windows, including obsolete Windows files and items in the Recycle Bin. The steps are as follows:

1. This is the first step. Click Disk Cleanup on your taskbar.
2. This is the second step. Then choose a drive to be cleaned.
3. Three. You will be able to see how much space you will clear when you use Disk Cleanup. Aside from the Windows ESD Installation Files, none of them are at risk if deleted. This can be left unchecked.
4. The fourth step is here. Additionally, you can delete additional files if you select Clean up system files to delete (see step 2), which offers more deletion options.

You can speed up your computer with Disk Cleanup, one of the best ways to clean Windows. Does Mac OS have a similar feature?

You can free up storage space on your Mac by using Mac’s built-in cleanup app, Optimize:

1. The first step is taking action. Then click the About This Mac icon in the upper-left corner.
2. This is the second step. Click Manage and then Storage.
3. This is the third step. The Optimize Storage link can be used to get rid of large files, such as movies and TV shows.

This page allows you to empty the Trash automatically and move files to the Cloud. You can utilize Optimize to free up disk space and make space for new files on your Mac.

1. Delete temporary files

If you want to remove temporary files created by Chrome or another browser, you need to do so from the programs themselves. You clear the cache on Mac and PC through the browser’s settings – get to the advanced section of the browser and look for the Clear Cache button. This button is usually adjacent to the button for deleting cookies.

There are numerous ways to increase the size of a cache. To gain more disk space, you can flush out all the data your browser stores automatically on your computer.

1. Delete duplicate files

It is possible to handle the copying process manually or use a program that identifies duplicates for you. The use of an app ensures that you do not delete folders with similar names but different contents. The purpose of this article is not to delete precious memories but to free up disk space.

Can you remember all of this? A program that does everything for you would save you time and make things simpler. Avast Cleanup can help you. The Avast Cleanup tool lets you remove temporary files from the web browser and duplicate folders on Mac or Windows computers.

1. Uninstall applications

The removal of unneeded or useless programs on your computer can increase hard disk space. The money they receive from those software companies can help PC manufacturers lower their prices by installing bloatware on their machines. This results in a bit of saving but lots of irritations—time to eliminate the headache.

To make your PC have more disk space, you may want to delete unnecessary applications:

3. Three. Please select the program you want to uninstall by clicking it.

This guide shows you how to uninstall Mac apps that eat up space and free up storage disk space without using a third-party uninstaller.

You can also uninstall apps using bloatware removal software for PCs and Macs.

1. Configure System Restore

You can restore critical files lost by recent updates with System Restore. As long as you don’t need it, you can usually leave it as is.

Your hard drive reserves space for System Restore so it can function. The following steps describe how you can set aside space on your hard drive by using System Restore:

1. This is the first step. You can choose System protection or Create a restore point from the Taskbar. Select Create a restore point.
2. Using the highlighted window, click Configure.
3. The slider controls the Max Usage amount. It is generally best to leave the default settings untouched unless all other options have failed to work.

The decision is up to you: is a failsafe mechanism more important than increased disk space? Exercise caution before making a decision.

What is disk space, exactly?

The total amount of hard drive storage space is called disk space. There is no unit for describing the volume of space on a computer. As a result, your operating system uses a lot of memory, called disk space, for apps like Google Chrome.

Why should I free up disk space?

It would help if you regularly cleaned up your PC to reclaim some space on a drive that is 90% full, as this will not perform as well as one that is 85% full. The most popular programs generate a surprising amount of garbage. This could explain why your hard drive is 90% full. It’s a good idea to become familiar with how to free up disk space.

You should keep at least 15% of your disk space free to store temporary files. The browser stores the information from commonly visited websites, so over time, you can accumulate data from sites you haven’t visited for months. Your browser’s temporary files can be deleted so that the sites you visit can take up less space.

Windows updates also consume space. Removing old updates and one-time installation files will make way for new updates to be installed, further securing your computer.

The hard drive will automatically split files into small segments, and it will store them wherever it can if you don’t have enough storage space. The segments will be read once the file is opened. The PC may have difficulties opening large files otherwise. This can be solved by defragmenting your hard drive, but you’ll need extra space.

Additionally, if your RAM must offload some work to your hard drive, you will need some free space. It will speed up considerably when this occurs, although it won’t freeze since the hard drive is too full to help.

How to check disk space on Windows 10

Windows 10 offers an easily accessible disk space. The link below is to show you the amount of disk space your Mac has.

Frequently Asked Questions

Why is my local disk C full?

There is an error message stating that when your C: drive is full, Windows will prompt you with this message: “Low Disk Space. There is no more space available on the Local Disk (C:). Click here to see whether you can free up some space.”.

How do I delete unnecessary files from the C drive?

You can access the main drive (usually C: drive) by right-clicking it. It includes options to delete temporary files when you click on Disk Cleanup. There is also an option to clean up system files. You can then remove the categories by clicking OK > Delete Files.

Does compressing C drive slow it down?

To decompress a compressed file, the CPU must work more. The reading of compressed files might be faster if the hard drive is slow on a computer with a fast CPU. These compromises write performance, however.

What happens when you run out of disk space?

The answer to that question is simple: Your computer will work less efficiently. The reason for that is because when the memory on your computer runs out, it will turn to the hard drive space for “virtual memory.”
