Also check saves containing a '*' in the name.

Under Windows, '?' is a wildcard which can match a single character, like the regular expression /./ does. Going further, '*' matches at least one character, like the regex /.+/ (NOT /.*/) does.

It is possible that the wildcard is being passed to Windows, which either is confused, or did something which confused KSP.

I'm interested in the save file structure with a save with '\' in the name. In fact, check '/' as well, since that also works under Windows.

EDIT: The following characters can NOT be used in filenames and should be error-checked for in all file writing operations (named quicksaves, craft names, save names):

• '\' and '/' are path delimination characters (Quicksaves can use these for subdirs though)
• ':' is used as a suffix for protocols and special devices
• '*' and '?' are wildcards (see above)
• '<' and '>' are for redirection
• '|' is for piping
