Excel is sometimes making binary changes without adjusting date&time. For
instance, when I open a spreadsheet, choose save as to create copy, the md5
checksum of the original is changed, without a change in date&time.This is
causing me problems when I do a binary comparison to check the quality of my
backup copies. I have seen this also in older versions of excel and in other
ms office products, but most notibly in excel.
can someone confirm this behaviour? explain it? point me to a solution?
it should be impossible to change a file without changing date&time ..!!!
thanks for any help!
