It seems I'm unable to delete the "Pictures" folder in my user's root-folder. Actually I'm not surprised as I it seems to be a standard folder in OSX, but what has been done to prevent being deleted and apart from it being the default location for keeping iPhoto libraries/images (or other photo related apps), is there something special happening "under the hood" for that folder? I'm asking because I have a problem with Adobe Lightroom seeing it spelt all-capitalized "PICURES" while in reality, on my hard drive it's spelt "Pictures", so I'm concluding that there must be something wrong with that folder and got the idea to create a new folder (i.e. "Temporary pictures"), move all my photos over there, delete (the now empty) "Pictures" folder, then finally rename "Temporary pictures" to "Pictures. But like I said, "Pictures" seems to be a special folder and I don't want to potentially mess up something by forcing its removal (I haven't for instance attempted a forced removal using Terminal using the recursive removal command).
