In Windows 7 is there a native way to compress or zip files from the command line? I'd like to do it without installing any third-party utilities such as 7Zip.

Hi, You can use Compact command. For more information, please refer to the following article. http://technet.microsoft.com/en-us/library/bb490884.aspx Best Regards, NikiPlease remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.

Thanks for the reminder about the native Windows COMPACT.EXE. With the files I have I see it compresses to a ratio of about 2.3:1; with 7ZIP creating a .ZIP file the ratio is about 6:1. So there's definitely a difference but it's something we may be able to live with. Thank you.
