Finder’s access to remote filesystems will sometimes show stale data. I’m copying a 2.5GB file to an SMB share (Linux samba). While copying I look at a folder, then click the little down arrow to open the subfolder in the window. It shows no contents, it must be an empty folder! So go to delete, and then it pauses saying “deleting 5 items”. Ha ha, joke’s on me. Cancel the delete, try again. This time wait 3–5 seconds for the file content to list, and poof there are the files now. At least I cancelled the delete in time.
I’m not complaining that the remote filesystem is slow, particularly when a big copy is happening. No. I’m complaining that Finder is showing incorrect information.
