Yes, and in addition, if there's a bolt of lightning during the zip file
update, everything is toast.  My scheme uses 

   x=SysFileTree(pxd||'*.*',"stem",'SF','+****',targatt)

pxd is something like 'H:\'

targatt = '-****' to reset A bits or '*****' to leave them alone.

This builds a list of the new or changed files.  My full backups reset all
the A bits.
