When performing a file level restore, vRanger Pro normally shows the list of files excluding hidden files.  To work around this, you simply need to navigate to the directory where the file level restore is being mounted as the vRanger Pro service account.  (%USER PROFILE%\Local Settings\Temp\FLR)

For example – I have a Windows 2008 VM that I want to restore some data from C:\ProgramData.  In the GUI for File level restore I see this:

As you can see the directory ProgramData is not there, because it is hidden.  So I browse to the vRanger Service account’s directory (Administrator.Demo) and I can see mount from Windows Explorer.

If I open this and go to the same volume I will now see the folder that is hidden.

From here I can simply copy and past the folder or any files that I choose.  I hope this helps any of you that are looking for those hidden files!
