got my first mac when the mbp got updated, blah blah. so everything has been great until my computer locked up today. i was backing up using superduper to an external harddrive. it stopped and had an error with a file called "upnp.log" on my harddrive. i opened the file and it opened into console. i believe the file was zero kb and now is 46mb. anyways, my system locked up and i couldn't force quit console. well, at first i was able to click force quit by right clicking console on the dock but then the dock and menu bar (except spotlight) locked up too. i couldn't bring up force quit using the keyboard shortcut either. i didn't know what else to do so i powered off by holding the power button. also later tonight i ran software update and installed the newest security update. just now i noticed a folder on my harddrive called 'damagedfiles.' it's only 1.3mb and has 343 files in it. they all have the little arrow like they are an alias. does anybody know what this is? finder says it was created at 7:50 which is 8 minutes after i opened the "upnp.log" file. my computer seems to be running okay. just wondering what's going on. i know i can check logs in the console but i don't really know what i should be looking for. is it safe to delete? any guidance is appreciated. thanks.
