2136	FileSetAttrib adds Archive attribute when System or Hidden attribs are set	MrCreatoR <mscreator@…>		"Example:

{{{
$sFile = @TempDir & '\Test.txt'

$hFile = FileOpen($sFile, 2)
FileWrite($hFile, 'Text')
FileClose($hFile)

FileSetAttrib($sFile, '+H')
;~ FileSetAttrib($sFile, '+S')

ConsoleWrite('-> Attrib = ' & FileGetAttrib($sFile) & @CRLF)
FileDelete($sFile)
}}}

Run this and you see that Archive attribute is added for some reason.

If we use attrib command from cmd.exe no extra attribs are added:

{{{
Run(@ComSpec & ' /C attrib +H ""' & $sFile & '""', '', @SW_HIDE)
}}}"	Bug	closed		AutoIt	3.3.8.0	None	No Bug	FileSetAttrib Hidden System Archive
