Ok..just found the answer...View ...Power Users...sorry about the newbie question....was just looking in the wrong place! (Found a lot of other useful detail options at the same time)
You can have the column in both Details and Power modes. Just right-click one of the other columns and you'll get a list of available columns; it's under General.
You can also do it via Folder Options and/or Folder Formats. If you want it to be on all the time then please read the Folder Formats FAQ for instructions.
For some reason I still had to configure the option via Power user setting first....now it is available in details too.
the FAQ's are great...but sometimes the challenge is trying to figure out which section of FAQ to look in...thanks for pointing me in the right direction.
