Windows 10: Cant compress anything to a zip file, And windows just asks what app to open the selected file

hello, When I press the compress to zip option in the context menu, It just asks how to open the file. Ive done the standard sfc /scannow and the DISM commands, which didn't reveal errors, nor was the problem fixed. I'm also updated to the latest 23H2. Ive looked around and have tried all i could find, and nothing worked. Any help or info is appreciated. Thanks!

not able to open zipped and compressed files using windows 10

What is the default App set for the file type .zip at Settings > Apps > Default Apps > Choose Default by File type? Try setting 7Zip there to make sure it gets tried.

Next go into 7Zip File Manager in Apps list, try opening a zip file to see what happens.

Complete all other steps and report back all results.

 

Compress files??

using upx? to compress exe files
but you need to make it executable zip first then do upx

 

So I used KGB Archiver to compress a 10gb file into a 40mb file...

Exactly. Most compression programs change a series of 1s and/or 0s to a couple of digits, and stores the total file in a table of contents/index. If you've got a file with TONS of repeating digits, sure, but pictures? No way to get that kind of compression in the real world.


from an article on "How To Geek"

First, we installed Bastion and compressed its folder — about 863 MB in size of music, graphics, executable files, and various different types of documents:

• Zip (Windows 8.1): 746 MB (86.4% of the original size)
• Zip (WinZip): 745 MB (86.3% of the original size)
• RAR (WinRAR): 746 MB (86.4% of the original size)
• 7z (7-Zip): 734 MB (85% of the original size)

Next, we compressed Hotline Miami, which is 654 MB of data:

• Zip (Windows 8.1): 316 MB (48.3% of the original size)
• Zip (WinZip): 314 MB (48% of the original size)
• RAR (WinRAR): 307 MB (46.9% of the original size)
• 7z (7-Zip): 301 MB (46% of the original size)

I would not expect a great deal of change from those numbers in November of 2014 to now, nor would I expect any real-world files to come any where NEAR the compression rate of .4%.
