Use manual tagging: go to the folder concerned then CTRL-A, right-click and choose 'Manual Tagging' then choose your tag from the list. Finally click [OK] to apply.
To enable the option have a look at this KB, https://kc.mcafee.com/corporate/index?page=content&id=KB68160

Thanks for the feedback Chris. There are over 1000 files in said folder and I was really looking for a way to automate the tagging process. Do you know is there a way I can do that?
THe files are in a standard windows file share( \foo\blah\blah\*)
They are a mix of xls, ppt and pdf
No discernible common criteria that I know of other than they are sensitive
1. Create a tag called "Confidential" in your "DLP policy" console.
2. Create, in tagging rules section, a location based taging rule, pointing on that share that will tag those files with "confidential" tagg.
3. Verify the outcome of the rule with "manual tagging" option.
