//     (base name and full stop and extender) may use,
//     EXCLUDING  the zero-terminator
//     The is also the maximum length for a directory name

//		* characters in the (decimal) range 0 through 31
//		* less-than (<), geater-than (>), double quotation mark (")
//        pipe (|)
//		* Drive separator : colon(:)
//		* Directory separators : slash (/) and back slash (\)
//      * Wild characters : question mark (?) and asterisk (*)
//      Different file systems add extra limitations
//		FAT : left-square-bracket ([), right-square-bracket (]),
//		      semi-colon (;), equals-to (=), comma (,) and plus (+)
//			  Full stop (.) may only be used for extender speration
//		VFAT :
//		HPFS :

//	The infix _W_ means that wild characters are allowed and thus not invalid chars
//  The NULL-character cannot be checked using string functions and is therefore
//  removed from the invalid chars
