Powershell – How to unhide hidden NTFS folder? (option greyed out, maybe it’s a system hidden folder)

Grab Handle.exe (http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx) and, on the server computer, run a "handle -a" redirecting the output to a text file. Search that for the affected filename. That should at least tell you what process on the server computer has an open handle to the file. I'd be interested to know what process has a handle to it. (I'm wondering about anti-virus software as a possibility...)

My condolences for having to deal with GlobalShop, BTW.

Edit:

McAfee VirusScan 8, eh? Have a look at this: https://kc.mcafee.com/corporate/index?page=content&id=KB52156

It refers to Microsoft Office files, but it sounds suspiciously like it could affect any type of file. See also:

You can create a file like that for testing by typing the following, then hold the ALT and type 255 on the numeric keypad, then release ALT and press ENTER. This will create a filename with a hidden character at the end.

echo.>when_it_initializes.cs

However, the error message I get is:

more when_it_initializes.cs
Cannot access file c:\path\to\file\when_it_initializes.cs

I can delete it with:

del when*
