[英]Find size of folders in an array using PowerShell
I have an array of folders, called $FolderArray
. 我有一个名为$FolderArray
的文件夹数组。 It contains about 40 folders. 它包含大约40个文件夹。 Inside each folder are a bunch of txt
files. 每个文件夹中都有一堆txt
文件。 I want to loop through each folder to get the number of files in each folder, as well as the total size of each folder. 我想遍历每个文件夹以获取每个文件夹中的文件数以及每个文件夹的总大小。 I got the number of files in each folder to work, but for the folder size, it ends up outputting the file size of the last file in each folder. 我得到了每个文件夹中可工作的文件数,但是对于文件夹大小,最终输出每个文件夹中最后一个文件的文件大小。
I pulled this out of a larger snippet of my code, so if anything needs more clarification please let me know. 我从代码的较大片段中删除了此代码,因此如果需要进一步说明,请告诉我。 I appreciate the help! 感谢您的帮助!
$ProcessedLocation = "C:\Users\User.Name\Documents"
$FolderArray = gci -Path $ProcessedLocation | Where-Object {$_.PSIsContainer} | Foreach-Object {$_.Name}
Foreach ($i in $FolderArray)
{
$FolderLocation = $ProcessedLocation + $i
[int]$FilesInFolder = 0
Get-ChildItem -Path $FolderLocation -Recurse -Include '*.txt' | % {
$FilesInFolder = $FilesInFolder + 1
$Length = $_.Length
$FolderSize = $FolderSize + $Length
}
Write-Host $FolderSize
}
You are iterating over $FolderArray
twice, once in the foreach($i in $FolderArray)
loop, and then again inside the loop body: 您要遍历$FolderArray
两次,一次是在foreach($i in $FolderArray)
循环中,然后是在循环体内:
foreach($i in $FolderArray){
Get-ChildItem $FolderArray # don't do this
}
If you want to look into each folder in $FolderArray
individually, reference the current variable (in your example that would be $i
). 如果要单独查看$FolderArray
每个文件夹,请引用当前变量(在您的示例中为$i
)。
I would recommend saving the output from Get-ChildItem
to a variable and then grab the size and count of the files from that: 我建议将Get-ChildItem
的输出保存到变量,然后从中Get-ChildItem
文件的大小和数量:
# keep folders as DirectoryInfo objects rather than strings
$FolderArray = Get-ChildItem -Path $ProcessedLocation
foreach ($Folder in $FolderArray)
{
# retrieve all *.txt files in $Folder
$TxtFiles = Get-ChildItem -Path $Folder -Recurse -Include '*.txt'
# get the file count
$FilesInFolder = $TxtFiles.Count
# calculate folder size
$FolderSize = ($TxtFiles | Measure -Sum Length).Sum
# write folder size to host
$FolderSizeMB = $FolderSize / 1MB
Write-Host "$Folder is $FolderSizeMB MB in size"
}
