When Explorer opens the compressed packet, it becomes slow.

Justify Explorer, No i don't think i would be able to do that.

Please use 7-zip to open archived files instead of explorer, because your machine becomes sluggish.

Other reasons as to why you should use 7-zip instead of explorer, see below.

• High compression ratio in 7z format with LZMA and LZMA2 compression
• Supported formats:
  
  • Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
  • Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.
  
  
• For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
• Strong AES-256 encryption in 7z and ZIP formats
• Self-extracting capability for 7z format
• Integration with Windows Shell
• Powerful File Manager
• Powerful command line version
• Plugin for FAR Manager
• Localizations for 87 languages

Or are you dead set to having all of your archived files open up in explorer?

At least I need to use it (Explorer), at least I will not use rar or 7z to manage files. Then, in the course of my use, it may become very slow. I want to try to solve this problem.

Forgive my curiosity- whilst I don't see the slow responsiveness you're seeing, I do see something strange. If the file explorer window is not maximised, and I open a zip in that window, and try to select (rectangle) starting in empty space, the cursor jumps bottom right, completely out of that window. Do you see that?

If I first select one of the displayed files, then use rectangle selection, it works.

Thanks.

In fact, I just used the mouse to make rectangular selection, and it became very slow. I'm surprised you didn't find it.
When I slide the rectangular selector, look at the CPU usage, and you can also see if the rectangular selector follows the mouse.
Of course, you probably haven't noticed that when I use Explorer for forward or return operations, it becomes very slow. Everything starts with a zip.

Could be we're using different builds- as you can see, I use 1709. Also different software installed.

Either way, there's something obviously wrong with the way file explorer is handling zip's associated with it. As I've not used that this is the first time I've encountered it- and I recall no similar reports.

Which is your Windows build?W
indows key + R, winver.
Is the performance the same after a clean boot, and after disabling all shell extensions? (E.g. using Shellexview (free), hiding all MS extensions first).

I don't think there is any problem with Explorer as the default opening option of zip. Of course, it is having problems now, you can say so.
I think the reason you are not affected may be hardware, when the hardware is strong enough, the system performance problems will be covered up.
They've added a lot of performance-impacting features to Win10 that could be the root cause of the problem, such as memory compression, pre-reading, and various security features.
