I have some trouble with cmd.exe. I use it sometimes to create files and write there the output. But if I try this:

wmic logicaldisk get name, freespace >> output.txt
echo %date% >> output.txt

And I start it two to three times, I get an output.txt like:

FreeSpace    Name  
17990881280  C:    
             D:    
㠱〮⸴〲㈱ഠ䘊爀攀攀匀瀀愀挀攀    一愀洀攀  ഀ਀㄀㜀㤀㤀　㠀㠀㄀㈀㠀　  䌀㨀    ഀ਀             䐀㨀    ഀ਀㄀⸸㐰㈮㄰′਍

Well, the Chinese text there looks funny, but I would like to see the date. I think somehow the encoding is changed with date. Everything is fine and I get the date if I do echo %date% >> output.txt alone.

I would like to get the wmic output and the date.

What should I do?

    WMIC has some weird output. I’ve seen a discussion where it was said WMIC uses unicode, but I think the situation is more complicated than that. If I capture WMIC output to a file and use a hex editor, I see an extra carriage return at the end of each line. I am completely at a loss as to how the date content is converted into gibberish when the output.txt is typed. (codepage issue? but how?) On my machine I get question marks where the date should be.

    I was able to fix the problem by using

    wmic logicaldisk get name, freespace | more >>output.txt
echo %date%>>output.txt
