General/common guidelines

Advice: Make files names lowercase and without any "strange" characters (space, diacritical marks, etc). Keep it simple and survival. Lowercase in not mandatory, it's just a good practice (in Linux similar uppercase and lowercase files can co-exists in same directory, in Windows this is not possible).

Mentioned files must be inside same directory where definition file sits. Don't use paths! Neither relative path nor absolute paths. They may broke.
