  Hello,

  We have 3 separate files that has been through encryption, base 64 encoding and as a last step they need to be concatenated. I have been using PowerShell for every other step in the process and now am trying to use PowerShell for concatenation as well.

  I was successfully able to do so by using the following command:

  Get-ChildItem path1\'+filname+'ph.enc.b64,  path1\'+filname+'.enc.b64 | ForEach-Object {gc $_; "."} | out-file path1\'+left(filname,7)+ ';
  type path1\'+left(filname,7)+' , path1\'+filname+'_pse.enc.signed.b64  > path2\'+Filname--+'.enc'

  Problem with this process is it creates a newline and carriage return characters before and after every "." separator. When I created the 3 source files individually I explicitly converted them to ASCII using "[System.Text.Encoding]::ASCII.GetBytes" before converting into base 64 format. But when I ran the above code for some reason the contents became UTF8 encoded. This was pointed out by the data host to whom we send the files. 

  my powershell version is 2 ,s o I could not use "-nonewline" option after out file option. 

  if the contents of 3 files are essentially in the following order:

  firstfile secondfile thirdfile

  I need an output that will look like :

  firstfile.secondfile.thirdfile

  Any help or guidance will be highly appreciated. Thanks.

  Kindly note that on my personal laptop I have PowerShell 5 and I could write the following command which works but on our server it is Powershell2 hence the following will not work there.

  $fileName1 = "path1\xyz.tar.gz_passphrase.enc.b64"  ;
  $fileContent1 = get-content $fileName1;
  #$fileContentBytes1 = [System.Text.Encoding]::ASCII.GetBytes($fileContent1);

  $fileName2 = "path1\abc.tar.gz.enc.b64"  ;
  $fileContent2 = get-content $fileName2;
  #$fileContentBytes2 = [System.Text.Encoding]::ASCII.GetBytes($fileContent2);

  $fileName3 = "path1\def.tar.gz_passphrase.enc.signed.b64"   ;
  $fileContent3 = get-content $fileName3;
  #$fileContentBytes3 = [System.Text.Encoding]::ASCII.GetBytes($fileContent3);

  New-Item -Path path2\newfile.tar.gz -ItemType FIle -force

  #[System.IO.File]::WriteAllText("path2\newtest" + ".b64",$fileContentBytes)
  Add-Content path2\newfile.tar.gz $fileContent1 -NoNewline

  Add-Content path2\newfile.tar.gz -Value "." -NoNewline;
  Add-Content path2\newfile.tar.gz $fileContent2   -NoNewline;
  Add-Content path2\newfile.tar.gz -Value "." -NoNewline;
  Add-Content path2\newfile.tar.gz -Value $fileContent3 -NoNewline;
