How can I view the allocation unit size of a NTFS partition in Vista?
Open an administrator command prompt, and do this command: fsutil fsinfo ntfsinfo [your drive] The Bytes Per Cluster is the equivalent of the allocation unit.

Individual components of a filename (i.e. each subdirectory along the path, and the final filename) are limited to 255 characters, and the total path length is limited to approximately 32,000 characters. However, on Windows, you can’t exceed MAX_PATH value (259 characters for files, 248 for folders). See http://msdn.microsoft.com/en-us/library/aa365247.aspx for full details.
