File or folder naming

Intro

This is not a serious issue. I was curious wheather using hyphen(-) in file nameing good or not. So, I searched and found an answer.

Good Naming

this is a range of characters that can be considered safe:

Letters (a-z A-Z) - Unicode characters as well, if needed
Digits (0-9)
Underscore (_)
Hyphen (-)
Space
Dot (.)

The forbidden printable ASCII characters are:

Linux/Unix:

/ (forward slash)

Windows:

< (less than)
> (greater than)
: (colon - sometimes works, but is actually NTFS Alternate Data Streams)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)

As Mac is considered under unix family, I guess this works with Mac too.
