Powershell 之批量获取文件大小的实现代码（powershell读取文件内容）居然可以这样


$startFolder=”D:”
$colItems=(Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $True} | Sort-Object)
foreach ($i in $colItems)
{
$subFolderItems=(Get-ChildItem $i.FullName -recurse | Measure-Object -property length -sum)
$FileSize=”{0:N2}” -f ($subFolderItems.sum / 1GB)
$Unit=’GB’
if($FileSize -lt 1)
{
$FileSize=”{0:N2}” -f ($subFolderItems.sum / 1MB)
$Unit=’MB’
}
write-host $i.FullName ‘ — ‘ $FileSize $Unit -fore green
}
