File names in the Windows file system are not case sensitive; in Linux 
they are. In Linux you can actually have two different files called 
test.txt and TEST.TXT:
[blogcosm at web8 py]$ cat > test.txt
this is a test
[blogcosm at web8 py]$ cat > TEST.TXT
THIS IS ANOTHER TEST
[blogcosm at web8 py]$ cat test.txt
this is a test
[blogcosm at web8 py]$ cat TEST.TXT
THIS IS ANOTHER TEST

Probably the best solution is to get used to it :-) but you could check 
for other files in the dir whose name matches ignoring case and open 
that file if there is a unique match.
