You, with Spamiky, are missing the point that the OP asked for the files to be made unavailable. You have to replace the Variant index pages. You would also have to block ../index_htm_files/xr_files.txt as this lists all the pages and assets still there.
Ideally, you need to devise a strategy to ensure all locally cached data is purged.
Password locking all assets, files and folders is the sanest mechanism.
