    Hi, 

    I tried to append blank lines to an existing file, but all I got are square-box looked chars at the end of the file. 

    I must have done it wrong. What's the correct way doing that?

    Thanks

    "`n`n" | Out-File -FilePath $File -Encoding "ASCII" -Append

    Well, a quoted string is going to have a implicit line terminator, so

    "" | out-file $file -append -encoding ASCII

    is going to output a single empty line to the end of $file. If you want two empty lines, you probably want this:

    "`r`n" | out-file $file -append -encoding ASCII

    Also not that I used `r`n (carriage return followed by line feed), not `n`n (two consecutive line feeds).

    thanks. Did you give it a try (of 
    "`r`n" | out-file $file -append -encoding ASCII
    )?

    Yes, I tested it before I posted it and it worked for me.

    Somehow it never worked for me. I got square-box looked chars at the end of the file no matter what, until I deleted the existing file. and all of sudden everything works now. 

    Thanks.

    That can happen if you have a mismatched group of new-line characters in a file, depending on what editor program you're using to view/open the file.

    I guess so. 

    Thanks.
