excel is making binary changes without adjusting date&time
Hello,
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!

I haven't looked into this very closely, but I think that excel (all of the
office programs???) keeps track of last access. If you open a file, then click on File|Properties|statistics tab (in xl2003 menus), you'll see a date accessed entry. Maybe that's the value that's changing your checksum???? king8nl wrote: Hello, Excel is sometimes making binary changes without adjusting date&time.
