Case sensitivity in file calls

I notice when hexediting DLL calls in Pocket PC apps (to get them to work in H/PC 2000/Pro) that the filenames and/or extensions are sometimes in lower case and sometimes in upper case. I wouldn't think that this makes a difference, except that the uppercase and lowercase letters are respresented by different hexadecimal values. Does letter case matter?

(Side note: I notice that some filenames show in different cases when viewed on the PC v on the CE device - eg, lowercase on the PC but uppercase on the device even though the latter shows filenames in both cases.)

no, they are not case sensitive. they are file names so why would they be like that never mind the hexa values either

cmonex. In linux case DOES matter.
But any windows platform I'm aware of (and DOS as well) is case insensitive.

I knew that's true for DOS, but I wasn't sure with CE. I have vague recollections of seeing in another thread that on-device application files and PC installer files have the .exe file extension in different case settings (ie, one's .exe while the other is .EXE).

nope, that must've been some misunderstanding.

just try to create a file with a name identical to another already existing one, just using different case... you will see you can't have both files
