Outcome

In order for your computer to please you with performance and quality of work, you need to periodically clean the registry. To be 100% sure that the removal will not bring any harm, you should have a slightly advanced understanding of how a computer works. When using such software be sure to make backups. If something went wrong, be sure to write in the comments and we will provide you with all possible assistance!

In the course of its operation, the operating system creates a lot of temporary data that is stored on the disk (usually drive C) in the form of files and registry entries. These can be service pack files, archivers, shadow copies, content downloaded from the Internet, etc. They behave similarly third party programs, such as browsers that store website data in a cache. Some temporary files are deleted automatically after a certain time, others remain on the disk until they are deleted forcibly.

If the user does not regularly maintain and clean drive C, free space it becomes smaller and smaller, to the point that the disk eventually turns out to be filled with temporary files to the eyeballs, which excludes further writing of any data to it and reduces its performance. There are two ways out of this situation - either increase the size system partition at the expense of the user volume, or perform its comprehensive cleaning, which is more preferable. Let's see how to free up space on Windows 7/10 local disk C.

What can be removed if the disk is full

The system volume contains many important files that ensure normal Windows work, therefore, its deep cleaning should be approached with the utmost care. What can be removed from the C drive to free up space and not break the system? All its content can be conditionally divided into three groups. The first includes files that can be deleted without any fear. The second consists of files, the removal of which, although it will not harm the system, but under certain circumstances can still cause certain problems. The third group includes files that cannot be deleted, as this can make programs and the system inoperative. You can clean drive C without negative consequences by deleting:

• Contents of the Cart.
• Library catalogs.
• Folders and Downloaded Program Files in the Windows directory.
• Cache of browsers and some third-party programs.
• Icon sketches.
• Logs and memory dumps for system errors.
• Old Chkdsk utility files.
• Bug reports.
• Files created by the Windows debugger.

With some care, you can delete shadow copies () created during the installation of updates and stored in backup copies, files of previous system installations (Windows.old folder), unnecessary components and applications, folders of uninstalled programs in the ProgramData, Program Files and Roaming directories, MSOCache folder Microsoft Office. If quick start is not used, you can delete the file hiberfil.sys in the root of drive C, after disabling these functions in the settings. It is acceptable, but not desirable, to remove the swap file pagefile.sys. Other files and folders on the C drive must not be deleted so as not to disrupt the system.

Cleaning up junk and temporary files using Windows tools

To begin with, let's see how to clear the C drive of unnecessary files in Windows 7/10 using the operating system itself. For this purpose, Windows has a built-in utility. cleanmgr.exe, which can be launched both through the properties of the section being cleared, and through the Run dialog box. After the utility scans the disk for obsolete files, check the boxes on the Disk Cleanup tab and click OK.

If you click the "Clean up system files" button, reports, device driver packages, error dumps, and additionally, restore points, with the exception of the latest one, will become available for deletion.

For a deeper and more thorough cleaning of disk C from garbage, you can use the built-in console utilities Dism and vssadmin. The first allows you to delete temporary data from WinSxS folders, including backups created before installing Windows updates. To do this, use the following commands, executed in the CMD console launched as an administrator:

1. DISM.exe /online /Cleanup-Image /StartComponentCleanup
2. DISM.exe /online /Cleanup-Image /SPSuperseded
3. vssadmin delete shadows /all /quiet

The first command does the same as the cleanmgr.exe utility, only more carefully.

The second removes all standby updates from the WinSxS folder.

With the third command, you can delete all restore points, including the last one.

However, you should use these tools with caution, because after executing the indicated commands, you will no longer be able to roll back the system to a working state or previous version.

Note: before clearing the WinSxS folder, it is recommended to set it to its true size, thereby making sure that it really needs to be cleared. To do this, you need to execute command line command Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore and compare the actual size of the component store with the size indicator in the Explorer properties.

After windows updates up to more new version a folder appears in the root of drive C Windows.old, which can take up a lot of disk space.

The contents of this directory are represented by copies system files installation of the previous Windows versions. If you are determined not to return to old version system, the Windows.old folder can be deleted. This is done again either using cleanmgr.exe or using the command line. In the first case, you need to find and mark on the "Advanced" tab the item "Previous Windows installation", in the second - run in the console running as administrator cmd command rd /s /q c:/windows.old.

You can get some extra space on the C drive by removing unused components, the same ones that the classic Add/Remove Programs applet provides access to.

The regular Dism utility is also involved here. To select and uninstall an unused Windows component, run the following two commands in an elevated CMD console:

1. DISM.exe /Online /English /Get-Features /Format:Table
2. DISM.exe /Online /Disable-Feature /featurename:NAME /Remove

The first command lists all components in the system, the second deletes the selected item. AT this example its name must be substituted for the element of the string NAME.

Manual removal of programs and files

Except for universal Windows applications 8.1 and 10, almost all desktop programs are installed in the folder Program Files. If the program is no longer needed, it should be deleted so that it does not take up space on the disk, but you need to do this either with the help of a standard uninstaller or with the help of special third-party programs. However, after uninstalling applications, their folders with configuration files, the weight of which can reach several hundred megabytes. Such data must be deleted manually.

Let's say you removed Microsoft computer Office or Skype and you also want to get rid of all their "tails" remaining on the C drive. To do this, carefully check the Program Files and ProgramData directories in the root of drive C, as well as the folders C:/Users/UserName/AppData. If the folder name is the same as remote application, it can be removed.

With the AppData folder, things are a little more complicated. This hidden directory contains three subfolders: Local, LocalLow, and Roaming. The first stores files created during the operation of various programs. You cannot clear it entirely, as this will certainly lead to the loss of saved application settings, however, half-empty folders of uninstalled programs can be safely deleted. You can also safely clear the contents of the folder located in it. Temp.

The same applies to the LocalLow and Roaming folders, only those directories that belonged to previously uninstalled applications can be deleted from them.

Note: clearing the contents of the Local, LocalLow and Roaming folders, you lose user settings and data stored in their cache. For example, after deleting its folders in the user profile, you will lose the current messenger settings and part of the message history.

As for the removal of universal applications, they are uninstalled by regular means of the system itself or CCleaner, which will be discussed below. You can also move some universal applications from drive C to drive D if they support this feature.

Transferring desktop programs to another volume is also possible, for these purposes there is special utility Steam Mover, which you can download from the developer's site www.traynier.com/software/steammover.

Using CCleaner

Many novice users are interested in how to remove junk files from drive C, using third-party programs, as well as which of these programs are more efficient and safe in this regard. These can be recommended CCleaner is a simple, fast, convenient, and most importantly safe Windows disk and registry cleaner. This program allows you to delete temporary data from the Internet and Windows itself, the contents of the thumbnail cache and DNS, Index.dat files, memory dumps, fragments of chkdsk files, various system logs, obsolete prefetch files, and a lot of minor data.

With CCleaner you can clean up invalid entries system registry, optimize , enable, disable or remove browser extensions, analyze content hard drives, search for duplicates and, of course, uninstall unnecessary applications, including universal ones.

The interface of CCleaner is very simple, so even a novice user can easily figure out its simple functionality.

Considering, however, that the main purpose of CCleaner is still cleaning, all its additional tools have limited functionality. If your C drive is clogged with something incomprehensible, and you want to find out what exactly, then for these purposes it is better to use specific utilities, for example, Scanner, JdiskReport or their analogues, showing more accurate information about the file structure of the media with the ability to navigate through subdirectories.

Other ways to free up space on the C drive

Clearing the Driver Store

The actions described above are usually enough to free up enough space on the system volume, but what if the C drive is still full? What else can you do to get more space? One option is to clear the contents of the folder FileRepository located at C:/Windows/System32/DriverStore.

This directory contains copies of device drivers that have ever been connected to the computer, and may also contain outdated versions of drivers. Before deleting driver packages from the FileRepository folder, it is highly advisable to create a complete list of them and find only obsolete versions in it, and leave the rest untouched. It also does not hurt to create a complete copy of all drivers installed on the system. To list the DriverStore drivers in a file, run the following command from an elevated command prompt:

pnputil.exe /e > C:/drivers.log

Compare the driver versions in the list and remove only the outdated ones.

To remove the selected driver, immediately execute the command in the console pnputil.exe /d oem#.inf, where # is the name of the driver in the list.

If you get an error in the console when uninstalling the driver, then the driver is in use by the system. It is not necessary to touch such a component.

As an alternative to the command line, you can use free utility Driver Store Explorer, just designed to remove old unused device drivers.

Disabling hibernation

Thanks to the hibernation mode, the user can quickly return to work in running applications, on the other hand, its use requires the allocation of system drive a significant amount of space slightly less than or equal to the amount of RAM. If the availability of free space on the hard drive is a priority for you, hibernation can be disabled by deleting the hiberfil.sys container file.

Launch the CMD console as an administrator and run the command in it powercfg -h off. Hibernation will be disabled and the cumbersome hiberfil.sys file removed.

Note: the hibernation file can be compressed by a maximum of two times with the command powercfg hibernate size 50.

Disabling the paging file

In addition to other hidden system objects, there is another file in the root of drive C, which, when certain conditions may be removed. This is the swap file pagefile.sys. This file plays the role of a RAM buffer and if some application does not have enough RAM for its work, its data is temporarily written to . Accordingly, if there is no swap file, a heavy application will slow down a lot or simply hang, waiting for faster RAM to be released. Therefore, disabling and deleting the paging file is not recommended, unless the computer has a very large amount of RAM.

If your PC has more than 10 GB of memory or you are not going to run resource-intensive applications, you can try to carefully disable swap. To do this, open Extra options system and on the "Advanced" tab in the "Performance" block, click the "Settings" button.

This will open another window. Switch to the "Advanced" tab in it, and then click the Change button in the "Virtual memory" block.

Uncheck the "Automatically select the size of the paging file" checkbox, turn on the "No paging file" radio button, save the settings and reboot. The pagefile.sys file will be deleted.

Deleting the MSOcache folder

Users who have installed the Microsoft Office suite have a hidden folder MSOcache, the weight of which can reach several gigabytes.

This folder is the cache office suite and contains files that you may need to restore Microsoft Office if it becomes corrupted. The MSOcache folder is not involved in starting Microsoft Office or working with documents, so it can be deleted in a standard way. Please note that if Microsoft Office is damaged for some reason, you will have to restore the package from the installation disk with its distribution.

Compressing the contents of the system volume

You can free up some free space on drive C without deleting anything at all. Instead, all system files can be compressed. To do this, just open the properties of drive C, on the "General" tab, check the box "Compress this drive to save space" and click "OK".

To compress system files in Windows 10, you can use the function Compact OS by executing one of two commands in the CMD console launched as an administrator:

• compact /CompactOs:query
• compact /CompactOs:always

The second command performs the same actions as the first, but in forced mode. It is used if you really want to compress system volume, and the first team rejects the operation, considering it inappropriate. The compression is completely reversible and to return file system to the normal state, it is enough to execute the reverse command compact /CompactOs:never.

In addition to NTFS compression, LZX compression is available in Windows 10, but it has a number of drawbacks, due to which it is not widely used. LZX compression is applicable to read-only files and directories, but an entire system volume cannot be compressed with it due to the risk of resulting in an unbootable system.

The speed of your PC can slow down significantly due to the growing list of files that are stored on your hard drive. Especially if it's the same drive that contains your operating system. Windows system.

Of course, modern drives may not suffer the same performance loss as older models with less throughput. Regardless, it's a good idea to work on unnecessary file growth on all of your PC's drives in a timely manner.

Which files should be selected for deletion?

1. Since the needs of each user will be different, there are no absolutes in the suggestions we can make here. We can provide information to help you decide which files to remove, but you will ultimately have to make the final decision yourself.
2. Downloaded program files. When you surf the Internet, websites typically place Java and ActiveX data on your disk. This may slow down your next visit to these sites if you remove them. We prefer to clear it as it has data from websites that we will probably never visit again on our hard drive. In addition, ActiveX and Java can pose a security risk due to the nature of the files and the way they are used.
3. Temporary Internet files. Every web page you visit is placed here for easy retrieval on subsequent visits. You may notice that when you go to a web page that takes a long time, when you click the back button, it loads instantly. This is the result of your browser retrieving the saved page directly from your hard drive. Deleting Temporary Internet Files will NOT delete saved passwords and login information.
4. Offline web pages. If you save your web pages for offline viewing, they are stored in this folder. If you delete them, you will need to visit the site to sync them again.
5. Basket. Everything is clear here without comment.
6. Service Pack Backup Files - If you completed a major update update windows update, these are the old files that have been saved, so you can uninstall the update package.
7. Temporary files - used to store temporary data while the program is running. The data is then deleted when the program closes. Sometimes leftover data will still be used by the program after a restart.
8. Miniatures. When you open a folder such as the Pictures folder, you will see small thumbnails for each image. They are stored here for immediate loading when the folder is opened. If you delete them, then the next time you open the folder, they will be re-created on the fly, slowing down the display speed as if it were the first time.
