Questions on deleting things from external hard (Time Machine)

[trackforlife7]

I don't know where else to put this but I set up a external hard drive to using time capsule. The hard drive is 500 gig and within 3 months worth of backing up I only have 287 gigs. How can I remove movies and other stuff off the hard drive? I tried deleting the a movie by looking into the back up folders on the hard drive but it keeps telling me it can't be modified.

unless you partition it ... it will eventually fill up with hourly backups

use 300 for TM and 200 for an external drive

how do I do partition it? Do I use boot camp? Also what is TM?

I use a simple 500GB WD My Passport external HD ... partitioned 300GB for TMachine and 200GB as storage
