    <p>I am using PowerShell 2.0 on a Windows SBS 2008 machine with the latest service packs. I have a two line script that finds all empty folders in a directory:</p> <pre><code>$a = Get-ChildItem E:\File_Server -recurse | Where-Object {$_.PSIsContainer -eq $True} $a | Where-Object {$_.GetFiles().Count -eq 0} | [what now?!] </code></pre> <p>The second line finds all folders that are empty, however I'm stumped on the last pipe. Here's what I've tried so far (keep in mind that the following were tried after the second pipe in the second line above):</p> <p><code>$_.move(F:\path)</code> Yes, I tried that. Yes, I'm a PowerShell noob. Of course, I received the error "Expressions are only allowed as the first element of a pipeline."</p> <p><code>move-item -destination F:\Path</code> I receive the lamest error ever: "Move-Item : Source and destination path must have identical roots. Move will not work across volumes." Seriously? What kind of asinine limitation is that?! Moving on...</p> <p><code>copy-item -destination F:\empty_folders</code> Apparently I can get around the limitation of move-item by using <code>copy-item</code> and then use <code>remove-item</code>. No such luck, however. I started the script with <code>copy-item</code> first. PowerShell didn't throw any errors, but also didn't do <em>any</em> thing else. It just sat there for the better part of an hour. No directories were moved.</p> <p><strong>Summary:</strong> How do I take the list of empty folders that I have and, <em>using PowerShell</em>, move those empty directories elsewhere (across volumes!) deleting the originals after the move? Notice the caveat "using PowerShell" as I've already thought about adding RoboCopy to the mix but would like to keep it within PowerShell.</p>

    1. COAre you avoiding `foreach` or `ForEach-Object` intentionally?

    2. COAre you wainting to maintain the same directory structure for the empty folders at the target location? If so, how will you know if a parent folder in the path was contained any files or not? If eg you get have c:\folder1\folder2\folder3\folder4 and folder1 and folder2 contains files, but folder3 and folder4 do not, does folder 3 count as an "empty" folder?

    3. CO@jscott I was under the impression that `ForEach-Object` was unnecessary since `Where-Object` fed the next pipe items one at a time.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
