Vista - Get size of folders and subfolders that meet a certain criteria

Im looking to use powershell to run through a directory tree and tell
me the size of all folders that are called desktop, but also the
subfolders of the desktop folder.

Any ideas.

Thanks
Claire

starting at c:\documents and settings

ps > dir -rec -include desktop | % { $_.pspath; dir $_ -rec | ? {!
$_.psiscontainer } |
measure-object -sum length | % { "{0:0.00}MB" -f ($_.sum /
1mb) } }

(split onto two lines for brevity)

sequence, split by pipe segments:

1) get all child items matching "desktop" and pass to next segment

2) for each item received, output its path; then get all child items
and pass to next segment

3) if item is not a container (e.g. file) then pass to next segment.

4) sum all the "length" properties of each object received, and pass
results to next segment

5) for each result, format to two decimal places, in megabytes.

Hope this helps,

and for the second part of your question:

dir -rec -include desktop | % { $_.pspath; dir $_ -rec | ?
{$_.psiscontainer} | % { $_.pspath } }

you should be able to understand this from the first explanation.

Hope this helps,

Try this:

function folderSize ([string]$path, [switch]$recurse)
{
$totalSize = 0
Get-ChildItem $path -recurse:$recurse -force | where {-not
$_.psIsContainer} | % {$totalSize += $_.length}
$totalSize
}
$path = "C:\Documents and Settings"
$desktopRoots = @(get-childItem $path -filter desktop -recurse -force |
where {$_.psIsContainer} | % {$_.fullName})
$desktopSubFolders = @($rootDesktop | % {get-childItem $_ -recurse -force |
where {$_.psIsContainer} | % {$_.fullName}})
$rootDesktop | foreach {"{0,8:n1} MB $_" -f $((folderSize $_ -r) / 1mb); $x
= $_; $desktopSubfolders -match [regex]::escape($_) | % {"{0,8:n1} MB
$($_ -replace [regex]::escape($x))" -f $((folderSize $_) / 1mb)}}

I came up with this one.
get-childitem c:\users -include Desktop -recurse | %{$name =
$_.fullname;get-childitem $_.fullname -recurse | Measure-Object -Sum Length
| %{"{1} is {0:n2}MB" -f ($_.Sum/1mb),($name)}}

Or in pretty form
$desktops = get-childitem c:\pathtofolder -include Desktop -recurse
foreach($desktop in $desktops)
{
$name = $desktop.fullname
get-childitem $name -recurse | Measure-Object -Sum Length | %{"{1} is
{0:n2}MB" -f ($_.Sum/1mb),($name)}
}

Sorry, there was a typo in the previous post.


function folderSize ([string]$path, [switch]$recurse)
{
$totalSize = 0
Get-ChildItem $path -recurse:$recurse -force | where {-not
$_.psIsContainer} | % {$totalSize += $_.length}
$totalSize
}
$path = "C:\Documents and Settings"
$desktopRoots = @(get-childItem $path -filter desktop -recurse -force |
where {$_.psIsContainer} | % {$_.fullName})
$desktopSubFolders = @($desktopRoots | % {get-childItem $_ -recurse -force |
where {$_.psIsContainer} | % {$_.fullName}})
$desktopRoots | foreach {"{0,8:n1} MB $_" -f $((folderSize $_ -r) / 1mb);
$x = $_; $desktopSubfolders -match [regex]::escape($_) |
% {"{0,8:n1} MB $($_ -replace [regex]::escape($x))" -f $((folderSize $_) /
1mb)}
}

Thanks for your help on this one its exactly what I want, just one
more quick question if i wanted to output it to a csv file but have
the size on the same line as the path what would i need to do. When I
tried to add the export-csv to the the pipeline i just get the sizes
not the paths.

Thanks again

Brandon thanks for that, I'm now trying to this to output to a file
but I need the path and total to appear on the same line, I have used
out-file -append but that still puts a line feed in. Any ideas on how
to achieve this.

Thanks again for your help

Claire

$path = "C:\Documents and Settings"
get-childItem $path Desktop -recurse |
where {$_.psIsContainer} |
select @{name = 'Path'; expression = {$_.fullname}},
@{name = 'Size'; expression = {"{0:n2}MB" -f ((gci $_.fullname -recurse |
measure-object -sum length).sum/1mb)}} |
export-csv Desktops.csv -NoType

get-content Desktops.csv

---------

In this case you can use calculated property/field '@{name = <string>;
expression = {<scriptblock>}}'
For an explanation on calculated property/field:
