Is there any way to force Finder to refresh its in-use information for gray (inaccessible) files?
I move infrequently used files from my Mac (OS X 10.6) to a Windows Server 2008 file server. I have recently found a large number of files which OS X's Finder shows as gray (like it would if the file was in the process of being copied). The files in question are all valid and complete: no corruption or missing data; in fact, I can access the files from Terminal or from a Windows computer without problem, but Finder still thinks they should be considered inaccessible.
I can "fix" the problem by copying the original file to a new name, deleting the original file, waiting a minutes or so, and then renaming the new file to the original name (if I don't wait long enough, the new file will become gray when it is renamed to the original name).
Basically, it seems as if the Finder has failed to clear some "in-use" or "incomplete" flag [conjecture].
So, back to the original question: how can this be fixed? Ideally, I would like to be able to scan the network drives and find and fix all the gray files via Terminal or Recursive operation, so I can fix them all without wasting a lot of time.
