Because some apps create MyFile.txt and expect to be able to access it later by myfile.txt. Adobe's applications, for example.

I had no idea. That's horrifying.

Open up the various folders of Adobe's software (on Windows). The DLLs are a mish-mash of all lowercase and upper-lower mixes. Heck, open up System32; the DLLs there are definitely not case-sensitive capable (`kbd*.dll' being one example). In fact, I bet you there's at least one program on your computer that accesses the Program Files using `C:\PROGRAM FILES (X86)' instead of `%programfiles(x86)%'. In fact, even environment variables aren't case-sensitive.
