Can you clean up compressed old files during Disk Cleanup?

There are several drawbacks.

1. Clean up the cache after the system disk is cleaned, and an appropriate amount of cache can speed up the reloading speed of the program and the web page. This will cause the frequently used** or programs to load a little slower. However, this one has little impact.

2. When cleaning, the log files of the system will be cleaned up, which will have a certain impact on the maintenance and diagnosis of computer failures. However, this item is generally more useful for administrators, and ordinary users are not greatly affected.

3. When compressing old files, it will take a lot of time to calculate which files to compress and the performance after compression. And in some systems, the Disk Cleanup program also becomes unresponsive during processing. Moreover, it has a certain impact on system performance (for example, the system needs to have a decompression process when the system wants to use these files again), and it has a greater impact on computers with CPU performance that is not particularly strong.

Nowadays, the capacity of hard disks is often hundreds of G, and the XP installation system partition is generally about 20G is enough, as long as the hard disk is not too small, there is generally no need to choose to compress old files.

Compress the files of the C drive, and you don't want to boot it up the next time you start it.

The built-in software of the system cannot be started.

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.

Generally, no, but disk cleaning will have certain risks, it is recommended to do disk cleaning as little as possible, because this is a high-load work for the hard disk, which has an impact on the life of the hard disk.

Disk Cleanup is a process of organizing your files, putting in place what you don't usually put in place, not deleting the original files, but also deleting temporary files.

Defragging is simply the reorganization of fragments of files in order. It can improve the file reading speed. Files are not deleted.

Usually not, just clean up some temporary files, but you have to choose well.
