Need help to locate the files along with size - powershell

Question

I wrote a script in powershell to locate the files in share drives which takes the names of files from a .txt file. The script is as below.
$Files= Get-Content lock.txt
foreach ($File in $Files) {
get-childitem -path Z:\lonmgb003_2 -Name $File -Recurse
}
Could someone help me with identifying size of file along with path. Thanks in advance.

Answer 1

The -Name parameter is a switch - it doesn't take an argument - and it causes Get-ChildItem to output just the file name and nothing else. The $File argument is instead being bound to the -Filter parameter.
Remove the -Name parameter and then use the Select-Object cmdlet to select just the path and size.
Since you have all the file names in an array already, you might as well use the -Include parameter to retrieve them all at once:
Get-ChildItem -Path Z:\lonmgb003_2 -Include $Files -Recurse |Select FullName,Length

Answer 2

You would need the Length and FullName properties of the files. You can do something like this.
$array= #()
$Files= Get-Content lock.txt
foreach ($File in $Files)
{
get-childitem -path Z:\lonmgb003_2 -Recurse | ?{$_.Name -like $File}
$obj = New-Object PSObject
$Size = [Math]::Round((Get-ChildItem -Recurse $_.FullName | Measure-Object Length -Sum -ErrorAction SilentlyContinue).Sum / 1MB, 2)
$obj | Add-Member -MemberType NoteProperty -Name "Path" $_.FullName
$obj | Add-Member -MemberType NoteProperty -Name "SizeinMB" $Size
$array +=$obj
}
$array | select Path, SizeinMB
What i have done is create a custom PS object that will store the FullName(precisely path) and Size of all the files. The use of -Name property doesn't help as it would just return you file name as a string and not the name as file (whose property you can use). Hence, a where-Object to match the file names in the text file. After your operation is done, the desired output is stored in an array named $array.
