I did not have it set so it had the value 'local before I changed it to nil now. I googled for the variable now and saw this: "If the variable w32-get-true-file-attributes is non-nil (the default), Emacs tries to determine the accurate link counts for files. This option is only useful on NTFS volumes, and it *considerably slows down Dired and other features*, so use it only on fast machines." Hmm... There is a suggestion to use it only on fast machines at the same time it is turned on by default. Shouldn't it be the other way around? Btw, I consider my machine to be quite fast even though it is a couple of years old. I suggest we change the default value of this variable to nil (or make the code faster). /Mathias
