They both return the same file because there's only the one item in a 
case agnostic filing system. It should be selected regardless of the case 
used to do so.

The following is based on the behaviour of Microware's OS/9, formerly 
quite a popular real-time OS, but I'm pretty sure that all case-
insensitive OSes would work the same way.

OS/9 allows you to use upper,lower or mixed case to name a new file or 
directory and gives it the name exactly as typed, but it does caseless 
comparisons when looking for an existing file or directory. The common 
convention was to use UPPER-CASE for naming directories and lower case 
for naming files and devices. Since directory listings are always 
lexicographically sorted, this means that directories will appear first, 
followed by files. However, commands that reference existing files and 
directories can be written entirely in lower case.
