REM -------------------------------------------------------------------------------------------------------------------------------
REM WRONG - @attrib match only files that have all attribute listed
echo %@attrib["My File",a]%
REM ... '1' if ONLY Archive bit is set
REM GOOD - Use p as 3rd param to make partial match
echo %@attrib["My File",a,p]%
REM ... '1' if Archive bit is set
REM -------------------------------------------------------------------------------------------------------------------------------
REM WRONG - %1 might contain space, but @attrib requires LFN with space to be surrounded with quote
echo %@attrib[%1,a,]%
REM GOOD - Use "%@full[%1]%" to force quote
echo %@attrib["%@full[%1]%",a,]%
