This is in fact a protection against collisions - for 
example:
www.foo.com/index.html
AND
www.foo.com/Index.html

can both exist at the same time on Unix systems, but 
NOT on windows systems, as files are case insensitive. 
In this case, these two files will be saved 
as 'index.html' and 'index-2.html'

You may also have (this is the most common case)
www.foo.com/
AND
www.foo.com/index.html

but the engine can not 'know' that these files are 
identical (the default / file could be default.html or 
default.php or gnzypw.gif)

Therefore, the engine may have to rename some files, 
into <name>-2.html, and there isn't any realy trick to 
avoid that. If you have multiple files with query 
strings, the engine will automatically generate a 
pseudo-random string added to the end of the name, but 
in your case this is impossible.
