Find and Delete Specific Files with Powershell

Greetings everyone
I am trying to figure a way to use Powershell to scan multiple directories to search and remove a specific file type. "._NH Speedway wide.mov" The issue I am having is that the file information following the underscore changes based on the parent file name. These files are created on a FinalCut Pro NLE system running MAC OS 10.5 and copied to a Windows Server 2008 R2. I have no issues with finding the standard ".mov" files with a scritp but I have not been able to list these type of files. Any ideas would be greatly appreciated. Here is the script that works for normal file extensions but not the ones I need to find:

# PowerShell script to list the ._xxx.mov Files on the server
$Dir = get-childitem \\xxx-xxxx\Media_Exchange -recurse
# $Dir |get-member
($List = $Dir | where {$_.extension -eq "._*.mov"}).count
$List | format-table name

What if you changed it to:

# PowerShell script to list the ._xxx.mov Files on the server
($List = get-childitem \\IP\Media_Exchange -recurse | ?{$_.name.contains("._")}).count
$List | ft name


Does that find the files you're looking for?

Hi Dale
Your edit does indeed return a list of files with other extensions, it does not return the list of .mov files.
Here is the script now:

# PowerShell script to list the ._xxx.mov Files on the SQL server
# $Dir = get-childitem \\xxx-xxxx\Media_Exchange -recurse
($List = get-childitem \\wcsh-sql01\Media_Exchange -recurse | ?{$_.name.contains("._")}).count
$List | ft name

Here is a snippet of the output:

Try this:

($List = get-childitem \\wcsh-sql01\Media_Exchange -recurse -filter "._*.mov" -force).count
$List | ft fullname

The addition of the -force parameter will show you any hidden files or protected system files that are possibly causing the issue with not showing .mov files.

The -filter parameter is our search filter, anything with ._ in the beginning and ending with .mov will be included

I've changed the ft to Fullname so it will show you the path and extension.

HTH,

You can add a pipe and remove-item cmdlet

($List = get-childitem \\wcsh-sql01\Media_Exchange -recurse -filter "._*.mov" -force).count
$List | ft fullname
$List | Remove-Item

Tested and works even throughout multiple directories without actually removing a directory.

Good luck!
