Time Machine, possible to delete stuff from external?

[crazycat]

When i got my hand on leopard it was a good time to upgrade my hard drive size, so i did. I used my old hard drive with an external enclosure and added a 1TB HItachi internal hard drive to my macpro. I had lots of docs, pics and music on my old hard drive so i dumped everything on my desktop which took up around 300GB worth of space.

Now my TM backup went from 180GB to 400GB, i do not need any of the files on my desktop i just placed them there so that i can organize them later. Is it possible to delete these large files from TM so that my external will not get full? Is there a way to go back in time and not add these files to my TM backups?

EDITED - If it helps i know the exact date i added these files and i only added them to my desktop.

When you're in Time Machine, if you go to whatever file it is you're looking to delete, then click on the little gear icon in the toolbar, there should be something in there about delete all backups of ___. That should get rid of every instance for that file in all the backups.

or

If there is nothing in TM or on that drive that you need... then format it and restart TM. I just did that with my MBP and it sure shrank the size of the TM drive after the first backup. I guess there are lots of ways to skin a cat.

and then I noticed your name... sorry.
