#2724 CLI fails on passwordless .Zip file that the GUI can extract & test without issue

[Christian Blackburn]

I have a zip file that I made in 7-Zip's GUI (7zFM.exe) that I'm unable to list the contents of using 7-Zip's CLI (7zr.exe). To be sure nothing happened to the zip I ran test and extract in the GUI and they both worked without issue. This archive is not password protected, so there doesn't seem to be any obvious reason for this failure.

Repro:
C:...>7zr l zip_files_test.zip

Result:

7-Zip (r) 26.05 (x86) : Igor Pavlov : Public domain : 2026-10-21

Scanning the drive for archives:
1 file, 1065 bytes (2 KiB)

Listing archive: zip_files_test.zip


ERROR: zip_files_test.zip : Cannot open the file as archive



Errors: 1

Expected:
The following files/folders should have been listed (any path that doesn't end in .txt is a folder):

• root.txt
• First
• First\Second
• First\nested_1.txt
• First\Second\Third
• First\Second\Third\Fourth
• First\Second\Third\Fourth\nested_4.txt

7zr does not support the zip format. Watch 7zr i

Hi Igor,

Thanks for letting me know.   Would you please consider adding this to your FAQ and adjusting the error message to "CLI doesn't support zip files"?

Thanks,
