Finder re-arranging files by last used and "blank" unnamed folder icons (high sierra 10.13.4)
i'm on high sierra on a 2015 mac air and for quite awhile now FINDER has been sorting files in a manner that seems odd. usually they are consistently sorted alphabetically.
now i see files getting sorted by LAST USED. just now i was in the DOWNLOADS folder and arranging information and the last folder i put a file in went to the top in "real time". in the past i have seen this behavior in apps online when i went to UPLOAD an image or a file i would see them shown in some order that showed them by the last used image file. i've also seen it happening a lot in DROPBOX folders.
this is sort of confusing to be able to track and a bit annoying to try to work around.
i ALSO sometimes see "unnamed" folders (on my desktop or elsewhere) which is basically a folder that has a name but the name has been hidden in some graphic way so all you see is the folder. if you click in it you can see the file name but when you are looking at it you won't see the file name. usually this goes away but it is also annoying.
