Uragan66, ну, так это тоже не «сохранение файла».

Код:

$d = '#EXTM3U'
$url = 'https://api.acestream.me/all?api_version=1.0&api_key=test_api_key'
[System.Net.ServicePointManager]::SecurityProtocol = @("Tls12","Tls11","Tls","Ssl3")

$aslist = `
    (Invoke-RestMethod -UseBasicParsing -Uri $url) |`
        ForEach-Object -Process {
            "#EXTINF:-1,$($_.name)"
            "http://127.0.0.1:6878/ace/getstream?infohash=$($_.infohash)"
        }
$oUTF8woBOM = New-Object -TypeName 'System.Text.UTF8Encoding' -ArgumentList $False
[System.IO.File]::WriteAllText('C:\Мои проекты\0335\acestream.m3u', ($d, ($aslist -join "`r`n") -join "`r`n"), $oUTF8woBOM)
