[Zope] localFS for existing files

Hi, I've a folder tree on the filesystem with around 75 sub-folders and 3000 image (jpg) files arranged in these folders. When I make a localFS object to mapto this folder, I'm able to browse the tree, but clocking on the individual files fail giving an error message saying "set_objTime failed"... However, if I upload something through localFS' upload feature, there is no problem. Any clues? Thanks Babu http://vsbabu.csoft.net/
