I am somewhat picky about my filesystem structures. I really, really dislike directories with capital letters.
I'm more used to Windows where there are a lot of "special" folders in the home directory where care must be taken when renaming folders.
I'm currently using Lion and trying to force myself to use OS X more often.
I would like to know if its safe to just rename the directories, e.g. Documents, Downloads, Public, Sites. Will the OS know where to look for the new directories? If not, is there a recommended way to do this?
