Question

我正在尝试创建一个可以报告指定文件夹的文件夹大小的脚本。

我输入文件夹名称后仍然收到此错误，我知道该文件夹存在。

此外，如果我没有收到此错误，那么我总是得到0 MB。

get-childitem : Cannot find path 'C:\WINDOWS\system32\downloads' because it does not exist.
At C:\Users\Erik\Desktop\powershell script.ps1:58 char:12

    + FullyQualifiedErrorId : PathNotFound, Microsoft.PowerShell.Commands.GetChildItemCommand

代码

$startfolder = Read-Host -Prompt 'Please enter the folder name:'

#check that input is not empty
if([string]::IsNullOrEmpty($startfolder)) {            
    Write-Host "folder name is NULL or EMPTY"            
} else {
    $folders = get-childitem $startfolder | where {$_.PSiscontainer -eq "True"}
    "folder Name`tfolder Size (MB)"
    foreach ($fol in $Folders) {
        $colItems = (Get-ChildItem $fol.fullname -recurse | Measure-Object -property length -sum)
        $size = "{0:N2}" -f ($colItems.sum / 1MB)
        "$($fol.name)`t$size"
    }
}

所以..我的电源壳有点可怕，但我已经为我工作了这个：

$startfolder = Read-Host -Prompt 'Please enter the folder name:'

#check that input is not empty
if([string]::IsNullOrEmpty($startfolder)) {            
    Write-Host "folder name is NULL or EMPTY"            
}

else {
    $subFolderItems = Get-ChildItem $startfolder.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum
    $startfolder + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"
}

输出如下：

test -- 2.65 MB

get-childitem：找不到路径''因为它不存在
