Take note of the use of characters and rules at all times when naming directories and files

Directories

You can change directory names, but do not use spaces in the installation directory name. Also, do not use common illegal characters, such as: / : * ? " < > |

Files

The name may contain letters (a-z), numbers (0-9) and some special characters, such as:

# & () + - = @ [] ^ ' () ~. A dot (.) can also be used except at the end; an underscore (_) can be used except at the beginning of the name.
