Recursively delete files with filter on subdirectories

I am trying to achieve a small cmdlet.
<Root>
<Dir1>
<Dir11>
- file1.txt
- file2.log
<Dir12>
<Dir2>
<Dir21>
- file3.txt
- file4.log
- file5.ini
<Dir211>
file6.txt
Lets say I want to remove all files except extn *.log from <RootDir>
excluding any files under <Root\Dir1\Dir11> and <Root\Dir2\Dir21\Dir211>
So my operation should delete file3.txt & file5.ini

The closest i could get to was this...
$rootDir = "F:\Test"
$excludeDir ="Dir1\Dir11", "Dir2\Dir21\Dir211"
$excludeExt = "*.log"
get-childitem $rootDir -exclude $excludeDir | foreach{ Get-ChildItem
$_.FullName -Force -Recurse -exclude $exclis
t1} | where {$_.attributes -ne "Directory"} | foreach ($_) {remove-item
-force -recurse $_.fullname}

Is there any way i can tweak this code to achieve what i need?

Try this (note: this wasn't tested):

$rootDir = "F:\Test"
$excludeDirs = "$rootDir\Dir1\Dir11", "$rootDir\Dir2\Dir21\Dir211"
get-childitem $rootDir\* -force -recurse -exclude *.log | ?
{$excludeDirs -notcontains (split-path $_ -parent)} | remove-item -whatif

Thanks Keith! That almost did it the trick.. I was able to make it work with
a minor modification
get-childitem $rootDir\* -force -recurse -exclude $excludeTypes | ?
{$excludeDirs -notcontains (split-path $_ -parent)} | where {$_.attributes
-ne "Directory"} | remove-item -whatif

I would change
where {$_.attributes -ne "Directory"}
to
where {$_.PSIsContainer -eq $false}

I guess I just dont trust attributes.

+1. It is more OO. :-)

With what Brandon mentioned I would simplify it to:

get-childitem $rootDir\* -force -recurse -exclude $excludeTypes |
?{!$_.PSISContainer -and ($excludeDirs -notcontains (split-path $_ -parent))} |
remove-item -whatif

For a more practical reason other than I don't trust attributes.

The previous version would delete Hidden Directory, Compress Directory, and
ReadOnly Directorys... along with any Directory that has any attribute at
all.

p.s. I KNEW I didnt trust them attributes

Hi all, I found this to be quite helpful as I am trying to accomplish
something very similar, but I would like a powershell cmdlet that would
delete all files in all subdirectories over a certain age. I don't need to
exclude directories but I need to only delete files older than 7 days. Can
anyone please help provide a sample of this? Thanks in advance.

get-childItem -recurse | where-object {!$_.PSIsContainer -and
$_.lastWriteTime -lt (get-date).addDays(-7)} | remove-item

....if the files are hidden or read-only include the -force parameter on both
Cmdlets:

get-childItem -recurse -force | where-object {!$_.PSIsContainer -and
$_.lastWriteTime -lt (get-date).addDays(-7)} | remove-item -force

Guess there is a small hitch in this logic.
If the directory i want to exclude has subdirectories, then this wouldnt
exclude the files on the subdirectories.
So if my $excludedirs contains "F:\test\d1", this command would still remove
a file "F:\test\d1\d11\file1.txt"
I'm afraid this is getting a bit complicated now Do i have to write
another loop to iterate through all the parent directories of a file..I am
wondering how this would affect performance if my directory heirarchy is
pretty long. Any ideas?
