File names displayed with random cases.

[Larry Hoover]

Does anyone know why some programs display Unix/Linux file name cases 
randomly, where some files will show as uppercase and others as 
lowercase?  There seems to be no distinction due to extension.   An 
example would be while browsing/exploring your PC into a mapped Unix 
drive, as you browse you will see some directories as uppercase, others 
as lowercase, and the same thing with file names.  They can be mixed in 
the same directory.  This causes problems when you are transferring 
files with Filezilla or other Windows based programs from Win to Unix.

Thanks in advance,
