Getting the size of all files within a folder tree

PowerShell – Getting the size of all files within a folder tree

24 Oct 2011 @ 6:59 AM

Last weekend I’ve been asked to write a script that will output the size of all files within a folder, and the files in all its sub-folders.
So, again something that’s possible with a one-liner Smile

Get-ChildItem D:\Software -recurse | Select-Object Name, @{Name=”KiloBytes”;Expression={$_.Length / 1KB}}

You don’t want the output to be in Kb but in MB? No problem…

Get-ChildItem D:\Software -recurse | Select-Object Name, @{Name=”MegaBytes”;Expression={$_.Length / 1MB}}

You can create script blocks for KB and MB ahead of time
$mb=@{Name=”MB”;Expression={($_.length/1MB)}}
$kb=@{Name=”KB”;Expression={($_.length/1kb)}}

Then use them as you need depending on the folder: dir c:files | select fullname, $mb

or even format the number

$mb=@{Name=”MB”;Expression={“{0:F2}” -f ($_.length/1MB)}}

Script blocks are definitely the way to go when you’re building a script since you can use them multiple times later in the script, but for a one-liner I can’t think of a reason to use it… or am I forgetting something?

I was merely suggesting defining scriptblocks so you could reuse them in other one liners. Suppose you want to check a diffierent folder and you want this to be in MB, just the the MB scriptblock in the select statement. I’m just trying to save some typing.
