a tip on how to delete folders in your time machine drive you excluded from back up

I discribe how to do this but basically you do the following.

1. launch the time machine from extras.

2. wait for the time machine controls to come up and the finder to appear.

3. already have selected the folder you wanted to remove from yoru back ups, for example dropbox.

4. navigate to the tool bar.

5. interact with it if you are using voice over.

6. press actions,

7. press delete this folder from all back ups.

8. confirm.

9. enter in your admin password

10. wait. The process should take between 30 minutes to an hour or 2.
