Well it sounds more fun than it is, but I had some problems deleting a directory the other week, it doesn't say it can't be deleted though. It starts off and if you look at the rate it's 0 byes a second.
I don't know what inspired me to do this but I knew there was only one file in there and it was a Quicktime file so I removed Quicktime and it deleted straight away.
I downloaded the latest Quicktime and assumed it was over. However when doing the ol' monthly uber backup I was unable to move certain files across hard drives (cut & paste) and when I looked into it - yes you guessed it it was a Qiucktime file!
Uninstalling Quicktime resolved the issue again but it's hardly an ideal solution, anyone else experienced this?
