(Testing on Windows XP Sp2)

I wonder if anyone can help me with this one.

I am testing a script as below to be run on our client servers to return the properties of any given directory (specified by client) for pre/post backup comparisons.

For testing I used the c:\windows directory on my machine simply because it contains a wide variety of file/folder attributes as opposed to standard directories containing just data.

$FolderList = gc "d:\folderlist.txt"
$Date = ( get-date ).ToString('yyyy-MM-dd')
$Report = New-Item -type file "$Date-directory.report.txt"
ForEach($TargetFolder In $folderlist) {
$OutItems = (Get-ChildItem $TargetFolder -include *.* -recurse -force | Measure-Object -property length -sum)
$OutFileNum = @(Get-ChildItem $TargetFolder -recurse -force | ?{!($_.PSIsContainer)}).Count
$OutFolderNum = @(Get-ChildItem $TargetFolder -recurse -force | ?{$_.PSIsContainer}).Count
"$TargetFolder : " + "{0:N2}" -f ($OutItems.sum / 1MB) + " MB" + " : Files=$OutFileNum" + " : Folders=$OutFolderNum" |
out-file $Report -append
}

So far I have noticed discrepancies (only very slight) in the returned number of files and folders.

The script returns the below results for the windows directory.

c:\windows : 4,516.26 MB : Files=23140 : Folders=2261

In windows, right-clicking and selecting properties returns this :

The differences in File and Folder counts is puzzling me. Am I doing something wrong in my script or is there an explanation at the OS level?

Other directories with 'normal' attributes and content seem to report ok by the way.

Couple of thoughts
Are there any hiiden files\folders that one is picking up and not the other?
Is the Windows folder itself being counted in one and not the othe?
Have you tried this on other folders?

So I was fooling around with the code a bit, and after some
refactoring I seem to be getting better results, but I'm actually not
sure why yet. I took out the formatting because I was trying to see
if the way MB was measuring megabytes (1000000 bytes vs 1024^2 bytes),
and I changed it so that Get-ChildItem is only called once to avoid re-
scanning directories. I also used tab-separated values because it
made it easier to open in Excel and suppressed errors from Get-
ChildItem.

$FolderList = @(gc 'folderlist.txt')
$Report = "$((get-date).ToString('yyyy-MM-dd'))-directory.report.txt"

"`nGetting a list of folders from folderlist.txt...`n"
"Folder`tSize`tFiles`tFolders`tErrors" > $Report

ForEach ($TargetFolder In $folderlist) {
if (-not $TargetFolder) { # skip blank lines
continue
}

$Results = @(Get-ChildItem $TargetFolder -recurse -force -
ErrorAction 'SilentlyContinue' -ErrorVariable DirErrors)

$OutItemNum = $Results | Measure-Object -property length -sum
$OutFileNum = ($Results | ?{$_.PsIsContainer -eq $false}).Count
$OutFolderNum = ($Results | ?{$_.PsIsContainer -eq $true}).Count

"$TargetFolder`t$($OutItemNum.sum)`t$OutFileNum`t$OutFolderNum`t$
($DirErrors.Count)"
"$TargetFolder`t$($OutItemNum.sum)`t$OutFileNum`t$OutFolderNum`t$
($DirErrors.Count)" >> $Report
}
