How can I clean up all the files that are not used on the disk?

Being able to ask such a question indicates that the user does not know much about the system program and the application. And do not easily clean up the hard disk garbage manually, so as not to hurt the system program and cause the system to not work normally.

1. In this case, it is best to install a tool software such as "garbage cleaner" and let it do the work for you to avoid the opportunity to make mistakes. If 360 Security Guard is installed in the system, it comes with a more complete "garbage cleanup" tool, which can be used to complete the system, applications, plug-ins, uninstallation legacy, registry and other garbage cleaning tasks with one click. At the same time, it also has a recovery function after clearing the error;

2. To manually clean up the hard disk garbage, you must clearly understand the purpose of the files to be deleted. For example, whether it is a subordinate of the system, or an application software, or a public file, whether it is data, data files, or real garbage. That is, you should know clearly what can be moved by the user and what cannot be moved, so as not to make mistakes or cause serious losses.

Hello! The computer is not so smart, the files you need and the files you don't need The computer can't make a judgment for you, you can organize or delete it by yourself, or you can use some antivirus software junk cleanup to clean up the deep junk files, but you can't delete all the files you don't want.

What they say is all nonsense listen to me.,There's an attachment in your start program - and then click on the system tool.,There's a disk cleanup in it.,After cleaning, you can compress old files [see if you can press it.,This function may not be available in some computers.,But it's better to take a look at it.,It's the easiest.,No money].

No. In fact, disk fragmentation should be called file fragmentation because files are scattered and stored in different places throughout the disk, rather than being continuously stored in continuous clusters of disks. When the physical memory required by the application is insufficient, the general operating system will generate a temporary swap file in the hard disk, and use the hard disk space occupied by the file to virtualize the memory.

The virtual memory manager will frequently read and write to the hard disk, resulting in a large amount of fragmentation, which is the main reason for the fragmentation of the hard disk.

There should be no doubt about tidying up your hard drive on a regular basis. If hard drive defragmentation does damage a hard drive, it's after an almost astronomical number of hard drive defragmentations.

Before deorganizing the hard drive, it is generally necessary to clean up the junk information, check for errors, and finally talk about defragmentation and optimization. Therefore, before you organize your hard drive, you should first do these things:

1. You should clean up the junk files and junk information in the hard disk. After the system works for a period of time, there will be a lot of junk files, there are temporary files generated when the program is installed, buffer files left when surfing the Internet, dll files left when deleting software or error files generated when forcibly shutting down, etc., it is recommended that "rookie" friends still use Microsoft's "disk cleaner" to do it for you, "old birds" can of course use some more powerful software or manual cleaning.

2. Check and fix errors in the hard drive. The first choice is still Microsoft's "Disk Scanner", although its speed is really not very good, but as long as you have enough patience, after a complete and detailed scan of the disk by this program, I believe that the vast majority of errors in the system have been fixed.

There are several ways to delete useless files from drive C:The first method: clean up with software.

Open 360 Security Guard and select the "PC Cleanup" option to clean all of the following sub-options one by one (currently only one by one).

If you feel that you are still not satisfied, you can choose to relocate the system disk, open the 360 security guard, and then click on the right-hand side, more into the functional area, if you do not add the C disk moving function, you can choose below, you can add it to the top at one point, and then click on the move, according to the requirements of the system to operate.

The second method: clean up with the disk program in the attachment. Click Start > All Programs > Attachments > System Tools > Disk Defragmenter, open a new dialog box, then select the disk you want to clean up, and click "Defragment".

After the cleanup is successful, Disk Cleanup Success is displayed in the session state.

The third method: My Computer - Property Cleanup. Double-click "My Computer", select C drive, right-click "Properties", open the "Properties" dialog box, select the "Disk Cleanup" button, and then open a dialog box, and then click OK after the file types you want to clean.
