FileSys¶

Get filename from path¶

$filename = Split-Path $filepath -leaf

Join path and filename¶

$filepath = Join-Path -Path "$dir" -ChildPath "$filename"

File without extension¶

$filename_without_ext = $file.Substring(0, $file.LastIndexOf('.'))

Check file exists or not¶

if (Test-Path -Path "$filepath" -PathType "Leaf") {}

List subfolder size¶

Get-ChildItem -force 'C:\Users\sma' -ErrorAction SilentlyContinue | ? { $_ -is [io.directoryinfo] } | % {
    $len = 0
    Get-ChildItem -recurse -force $_.fullname -ErrorAction SilentlyContinue | % { $len += $_.length }
     '{0,10:N3} MB  {1}' -f ($len / 1Mb), $_.fullname
}
