Here's how to clean your PC without deleting important files. Download the latest version of CCleaner here.
Why Remove Unnecessary Files with CCleaner?
Over time, Windows and your software create numerous temporary files. Browsers also save images, cookies, browsing histories, and site data. While these elements can speed up daily use, they can also take up significant disk space.
Removing unnecessary files with CCleaner can help you free up space. Cleaning can also erase traces of browsing on a shared computer. While it may not make a PC feel like new, it does eliminate temporary data that is no longer useful.
CCleaner provides simple options to analyze the system before launching the deletion. This step is important; it allows you to see the categories of files involved and avoid an overly broad clean-up.
Before starting, close any open browsers and the software you are using, like your office suite or media player. This way, CCleaner can detect and remove more temporary files.
Which Files Can CCleaner Remove?
CCleaner primarily analyzes files created by Windows, browsers, and certain programs installed on your computer. The elements offered vary depending on your system, software, and selected settings.
Here are the categories you will encounter most often:
- temporary files from Windows and applications;
- browser cache files;
- browsing history;
- cookies and site data;
- files in the recycle bin;
- logs, error reports, and diagnostic files;
- recent document lists;
- unnecessary installation or update files.
The browser cache deserves special attention. It contains local copies of images, scripts, and web pages. Deleting it frees up space, but sites may load a bit slower during the next visit as they need to recreate their cache.
Cookies also require caution. Some keep your preferences or your login to a site. If you delete them, you may have to log back into your usual services. For example, an online store or webmail may ask for your credentials again.
Safely Prepare Your PC Cleanup
A cleanup with CCleaner remains simple, but taking a few precautions can avoid unpleasant surprises. The principle is clear: start with the least risky options, and then broaden the cleanup if necessary.
Close Programs and Save Your Work
Save your documents before making any changes. Next, close any open browsers and applications. Some files remain locked as long as the associated program is running.
This precaution also improves the reliability of the analysis. CCleaner can then examine temporary files without conflict from active software.
Check Settings Before Deletion
Do not click immediately on the clean button. Look at the checked boxes in the sections dedicated to Windows and applications. Uncheck options you do not understand the effect of.
Pay particular attention to these data:
- saved passwords in browsers;
- cookies that are useful for your logins;
- open sessions in online services;
- recently downloaded files;
- history if you wish to keep it;
- recent documents that make accessing your files easier.
Labels may vary depending on the version of CCleaner. Always check the options displayed on your computer before confirming an action.
Consider a Backup for Sensitive Operations
Cleaning temporary files generally poses little risk if you check the checked boxes. However, more advanced functions require greater caution. Before modifying the Windows registry or uninstalling applications, create a backup of your important files.
You may also create a Windows restore point if you plan to modify system settings. This solution provides additional security in case of error.
How to Remove Unnecessary Files with CCleaner
The basic procedure occurs in a few steps. Take the time to read the results of the analysis so you maintain control over the files being removed.
1. Open the Cleaning Function
Launch CCleaner from the Start menu or its shortcut. Then, access the cleaning function, sometimes presented as a health check or a customized cleaning depending on the installed version.
The health check often aims for simplicity, providing guided cleaning. The customized cleaning offers more control over the files to remove. For a first use, choose the method that seems most readable to you.
2. Select the Items to Analyze
In customized cleaning, you will typically see an area dedicated to Windows and another for applications. Start with temporary files, cache, and recycle bin. These are the most useful options for freeing up space without altering your personal documents.
For browsers, keep saved passwords and important cookies if you don’t want to lose your logins. You may delete the history if you are using a shared PC. However, keep it if you need to easily retrieve visited pages.
3. Start Analysis of Unnecessary Files
Click the analysis button. CCleaner examines the selected categories and displays an estimate of the recoverable space. It also lists the types of data involved.
Do not just look at the total volume. Check the displayed lines. If you see a category you wish to keep, go back to settings and uncheck it. This habit protects you from deleting useful data.
4. Start the Cleaning
When the results are satisfactory, start the cleaning. CCleaner may request confirmation. Read the message before validating, particularly if it concerns browser data or files linked to programs.
The cleaning generally takes little time but depends on the number of files present and the performance of your disk. Once the operation is completed, check the summary. It will indicate what the software has removed.
5. Check the Result
Open your browser and main applications. Check that your usual sites are operational and that your important logins are still active. If you have deleted cookies, log in only on trusted devices.
You can also check the free space on your disk in the Windows storage settings. This verification allows you to measure the real effect of the cleanup.
Recommended Settings for Simple Cleaning
For most users, it is better to favor moderate and regular cleaning. Deleting everything indiscriminately does not always provide a real benefit. You primarily risk wasting time logging back into your accounts or reconfiguring some sites.
Here is a practical approach:
| Item to Clean | Advice | Possible Consequence |
|---|---|---|
| Temporary Files | You can delete them regularly | No notable impact in most cases |
| Recycle Bin | Empty it after verifying its contents | Files will not be easily recoverable |
| Browser Cache | Delete it if space is running low or if display issues arise | Pages may load slower on first access |
| History | Clear it on a shared computer if necessary | You will no longer find your visited pages |
| Cookies | Keep those from your important services | Deleting them often disconnects accounts |
| Saved Passwords | Keep them unless there's a specific need | You will have to enter them again |
This method suffices in most cases. It meets the main need: to remove unnecessary files with CCleaner while retaining your useful settings.
Clean Browsers Without Losing Access
Browsers quickly accumulate data. Chrome, Firefox, Edge, and other software store cache files, cookies, and histories. CCleaner can clean them, but each type of data serves a specific purpose.
The cache can be easily deleted. It may resolve certain display issues, for instance, when a site appears stuck on an old version. Cookies are more personal. They often remember your session or preferences. Do not delete them blindly if you frequently use the same sites.
If CCleaner offers a cookie management function, use it to retain those from the reliable services you regularly visit. Keep especially the cookies from your email, banking, or professional tools if it meets your security level. However, never let a browser store your sensitive logins on a public or shared computer.
Also, consider checking your password manager. If you use a dedicated tool, removing browser data will have less impact on your credentials. If your passwords are only stored in the browser, do not check the option that erases them without having a secure copy.
Should I Clean the Windows Registry with CCleaner?
CCleaner may offer a Windows registry cleaning tool. The registry contains many settings used by the system and software. This function often attracts users looking to speed up their computer.
However, cleaning the registry is not a miracle solution against slowdowns. Unused entries do not necessarily slow down your PC in a noticeable way. However, deleting an important key can create problems in a software or Windows.
Use this function only if you understand the type of correction being proposed. If you decide to use it, accept the creation of a backup when the software offers it. Keep this file in an easily retrievable location so you can restore changes if needed.
For regular use, focus first on temporary files, the recycle bin, and the cache. This approach is simpler and less risky.
Other Useful Functions to Use Discerningly
CCleaner may also include tools related to installed programs, Windows startup, or searching for large files. These functions can help you sort through, but they do not replace your judgment.
Uninstalling unused software can free up more space than cleaning cache. Uninstall only programs you recognize. Avoid deleting components with names that seem technical or related to hardware. If in doubt, first search for the program's name on its publisher's website.
Managing startup can also improve usability. Too many applications launched at startup can sometimes delay login. Disable non-essential software, such as certain update tools or convenience applications, but leave security elements and components necessary for your devices active.
The options, labels, and functions available change according to the version of CCleaner. Thus, always check the interface, terms of use, and proposed settings at the time of installation or update.
How Often Should I Use CCleaner?
You do not need to clean your computer every day. Excessive frequency may delete useful cache, forcing your applications to recreate it constantly.
An occasional cleanup is often sufficient when disk space decreases, after a long period of use, or before transferring a computer. You may also clean browsing data after a session on a shared device.
Adhere to a simple routine: first, check free space, then launch the analysis, and only clean the useful categories. This method remains effective and avoids unnecessary deletions.
FAQ About CCleaner and Unnecessary Files
Does CCleaner Delete My Personal Documents?
The standard cleaning primarily targets temporary files, caches, and selected data. However, always verify the options before starting the operation. Do not check folders or custom functions if you do not know what files they contain.
Can I Recover Files Deleted by CCleaner?
This depends on the type of file deleted and the operation performed. Files deleted from the recycle bin or cache data are not always easily recoverable. Therefore, check the results of the analysis before the clean-up and back up your important data.
Can CCleaner Speed Up My Computer?
CCleaner can free up space and delete temporary files. This may enhance comfort in certain cases. However, it does not fix all slowdowns. A nearly full disk, too many startup programs, old hardware, or malfunctioning software can also explain a slow PC.
Is It Useful to Delete Cookies?
Yes, in some cases, especially to protect your privacy on a shared computer or resolve login issues to a site. However, deleting all cookies will often disconnect you from your accounts. Keep those from reliable sites you regularly use if you want to maintain your sessions.
Conclusion
CCleaner allows for easy removal of unnecessary files, especially temporary files, caches, and recycle bin contents. For a safe clean, always analyze the selected elements before confirming. Start with the least sensitive data, retain your useful passwords and cookies, and avoid advanced modifications without a backup.
