Previously I have wrote a tip on how you can reclaim some disk space on your Mac, you can read that here. Following on from that is another little tip on how you could possibly claim back some more space.
iTunes keeps a copy of all podcasts etc that have not downloaded fully, so if you have many cancelled/failed downloads you may have a few 100Mb of space. I know this does not sound like much but every little helps. With little things like this, once I have heard about them, my OCD kicks in and I have to check and clean these things up regularly.
Default Location on the Mac would be
home -> Music -> iTunes -> iTunes Media -> Podcasts
Default Location on Windows would be
C:\Documents and Settings\username\My Documents\My Music\iTunes\iTunes Media\Podcasts
It's another place to check depending on how many you have, they may save some significant space. I will be following up again shortly with some more disk saving tips.
I am always interested in feedback so please feel free to add any comments, or you can mail me here. If you would like to submit a quick tip with full credit and links back to your site then also feel free to contact me.
