CaSE SensITIVY!

I downloaded/moved a client's site and then reuploaded it 
and several pages didn't work. Upon observation, half the 
pages didn't work because HTTrack changed the case of the 
files when downloading into all lower case names, while the 
references in the HTML referred to Upper/Lower 
combinations, which makes me scared to use this for 
important things w/o checking EVERY single page afterwords, 
which sort of defeats the purpose of automatically 
downloading.

I've looked everywhere, and I don't see that feature.  
Thanks so much.
