Finder shows strange letter and number codes instead of usual names for folders and stuff.
when I go anywhere in Finder, instead of showing the usual names of folders and such, I just see a strange letter and number code. For example, my 'empty trash' button now says 'N201' and my sidebar titles are now 'SD5,' 'SD8,' and 'SD7,' and when I right-click on anything, these number/letter codes come up in the drop-down menu, too. I have searched for any solution and nothing has worked. Please help!
