[gentoo-user] Change the case of file names

[Mick]

Hi All,

I backed up my wife's WinXP fs using K3B and I used default settings which 
unfortunately converted all file names to CAPITALS and shortened them to 8 
characters maximum, just like DOS would do.  Is there a clever way to change 
some of them back to lower case (in batches within given directorates) so 
that she doesn't have to do it manually one by one?  I do not want to change 
the access times, only the filename case letters.
