Windows has a command line tool fsutil which performs file system related tasks.  You must be an administrator on the local machine to use it.  There are a couple of commands that could speed up disk access.

By default, every time a file is accessed, even read, the last access date is updated.  This can be disabled.

fsutil behavior query DisableLastAccess
fsutil behavior set   DisableLastAccess 1

Every file created with a “long” file name, an 8.3 name is created and stored.  This can be disabled. [more]

fsutil 8dot3name query
fsutil 8dot3name scan /s c:
(check log file for registry entries for applications that might break)
fsutil 8dot3name set c: 1

Help text is available by just entering fsutil.  More complete documentation at
