I am trying to edit LucD's spring cleaning datastore script (Link) below to do a few things and need some help.
These are the things I'd like to do:
1. Report on all files and folders on the datastore, not just vmdks.
2. Support NFS datastores. if($ds.ExtensionData.Summary.MultipleHostAccess) should work.
3. Filter out .snapshot NetApp folders in addition to other "." prefixed system folders like HA, StorageIO, etc. (Would be nice to support regex filters.)
4. Exclude SRM and CBT folders/files.
function Remove-OrphanedData{
<#
.SYNOPSIS Remove orphaned folders and VMDK files
.DESCRIPTION The function searches orphaned folders and VMDK files
on one or more datastores and reports its findings.
Optionally the function removes the orphaned folders and VMDK files
.NOTES Author: Luc Dekens
.PARAMETER Datastore
One or more datastores.
The default is to investigate all shared VMFS datastores
.PARAMETER Delete
A switch that indicates if you want to remove the folders
and VMDK files
.EXAMPLE
PS> Remove-OrphanedData-Datastoreds1

PS> Get-Datastoreds* | Remove-OrphanedData
