Delete blank/empty line without writing to second file

[Champak]

Finding and deleting the line is not a problem, but the blank space left behind is. I really don't want to bother with writing to a second file, deleting and renaming the file. So is it possible to go through and remove the blank line like you do when looking for an actual string? Prefer, but not a must, to not bother with an array for this.

#include <File.au3>

$find = "Test Line"
$replace = ""
$filename = "C:\Test.txt"
_ReplaceStringInFile($filename,$find,$replace)

Found a way...if someone knows a better way please post.

$fileread = "testfile.txt"
$lines = _FileCountLines($fileread)
$hold = ""
For $x = 1 to $lines
    $search= FileReadLine($fileread, $x)
    If $search <> "" Then
        $hold&= $search & @CRLF
    EndIf
Next
FileDelete($fileread)
FileWrite($fileread, $hold)

do string replace, like here #463031

Not sure if it depends on how the file is formatted but i managed to simplify this by:

#include <File.au3>
_ReplaceStringInFile(@ScriptDir&"\filewithemptylines.txt",@CRLF&@CRLF,"")
