• The following characters are allowed in a folder name. 
  Upper-case and lower-case unaccented characters (character codes 65 to 90, 97 to 122)
  Upper-case and lower-case accented characters (character codes 257 to 416, 513 to 672)

ABC. 
• A reserved word (system variable names, built-in function names, command names, etc.) 
cannot be used as a folder name. 
• A number, subscript characters or the underscore (_) cannot be used as the first character 
of a folder name.
