Its very often that need to have a files/folders copied across as part of various automations in systems administration or infrastructure customization. Copy operations aren’t an issue for smaller sizes and/or less number of files. But, when you have to copy a large number of files/folders of around GBs in size, it becomes difficult job.
While setting file folder copy automation, you need a way to ensure that all the required files and folders or both are successfully to the destination. To assist that, you can check the count of the files/folder objects in both source and destinations apart from verifying the sizes.
Here is the PowerShell way to get the count of either only files/folder or both.
Since all in PowerShell are .Net objects the list of files/folder obtained using Get-ChildItem are also a set of object. You can use these objects properties to distinguish whether it’s a file or folder. The attribute/property to be checked is PsIsContainer.
Example: To list ONLY Folders/Directories recursively
Syntax: Get-ChildItem <Directory> -Recurse | where {$_.PsIsContainer}
PS C:> Get-ChildItem C:programdataSkype -Recurse | Where {$_.PsIsContainer} | Select-Object -Property Name | ft -auto
Name

For easier understanding at high level, you can simply refer to the number of objects found in source and destination folder
