Powershell: Combine multiple html files into one single html file

Question

I want to select and combine the content of all html files, from Folder 1, to a single html File from Folder 2.

Can this be done with PowerShell ?

Answer 1

to avoid problem of memory if you have lot of files:

1. i suggest you to use a streamer:
2. for html file, keep the utf8 encoding or you risk to loose some characters

$rootFolder = "c:\Folder1"
$outfile    = Join-Path -Path $rootFolder -ChildPath 'newfile.html'

$sw = New-Object System.IO.StreamWriter $outfile, $true  # $true is for Append
Get-ChildItem -Path $rootFolder -Filter '*.html' -File | ForEach-Object {
    Get-Content -Path $_.FullName -Encoding UTF8 | ForEach-Object {
        $sw.WriteLine($_)
    }
}
$sw.Dispose()
