#648 Unsupported Command Error when Opening .txt in 7-zip

[Evan Olmstead]

Good afternoon,

I am running into an issue in 7-zip where I am attempting to open a zip from a disk drive using 7-Zip File Manager, but after entering the password provided, I receive the attached error.

Any suggestions would be appreciated.

I should mention - this issue started after upgrading to Windows 11

Probably you have associated 7-zip to txt type files.

Thank you for your reply, Igor.

I've checked my associations in the 7-Zip Options menu - there does not appear to be an option to associate 7-zip to .txt files.

Windows allows to associate any program to any file extension.
You could call it by mistake.
