folder copy in Finder labels it as incomplete, though copying is completed I am getting this error much too often. I am copying a big number of files from a slow device (external hard drive) to my Mac. When the copy is completed, the last top folder is still marked as "incomplete".

 

I only managed to clear the mark by creating an empty folder with a different name (say "Folder2"), moving the contents of the folder (say "Folder") there, erasing the (now empty) folder "Folder" and renaming "Folder2". That all looks weird to me. Any suggestions?

Update: External drive is formatted in FAT32.
Try clicking 'Get Info' and see if it works for you. I know its stupid but it should work.
