Have you noticed how Windows Explorer sorts files with numbers in their name not how you would expect?  If you have items named IE4, IE401, IE5, you would expect them to be listed like this:
IE4
IE401
IE5

Instead, they are listed like this:
IE4
IE5
IE401

This is a little strange, since this sort order is used nowhere else by default.  Windows lists the entries in this order because the number 401 is larger that 5.  I got tired of this, so I finally did some searching and found an old Microsoft Knowledge Base article from 2007, http://support.microsoft.com/kb/319827, which still works on Windows 7.  You just create this registry entry: [more]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoStrCmpLogical"=dword:00000001

P.S.  There is -v option to the ls program on most UNIX type systems to sort directory output like this.  The v is for version - to list files with version numbers in order.
