why does robocopy say this file is older?
Robocopy shows (I think I used /MIR and /L)
2 M:\bk\laptopcopy\pics\
Older 79248 regular-expressions-cheat-sheet-v2.png
None of the time stamps seem to reflect that though.

[1] What does robocopy mean by tweaked, lonely and extra?
Which mentions documentation and http://theether.net/download/Microsoft/Utilities/robocopy.pdf and http://www.lordgoogle.com/downloads/robocopy/robocopy.doc
on a related note- i've heard synchronize it, beyond compare, as well as synctoy, are worth a look.. and these sync tools may be useful also when the directory structure changes.. so you don't get duplication .. these may help in letting you double check before copying. – barlop – 2016-12-20T00:57:39.303
The last set of time stamps seems to reflect older doesn't it? If M: is the Source and F: Destination. – N4TKD – 2013-04-28T00:46:07.170
@AlwaysLearning I don't think so. older is when source is older than dest. newer is when source is newer than dest. also I don't think it looks at access time(which that is), and, I think those access times are a case of Newer rather than Older. source>dest. See that table – barlop – 2013-04-28T07:15:08.403
Good point I move to SnycToy long ago, because of issues like these you may want to think about switching if you can. http://www.microsoft.com/en-us/download/details.aspx?id=15155
– N4TKD – 2013-04-28T12:27:12.993@AlwaysLearning thanks i'll consider that. Currently I use beyond compare to check my copies sometimes. but I think 'beyond compare' might also do a copy, or syncing or sync related operations. I actually haven't ever used robocopy for my backups and have only just tried it now. Normally I use fastcopy but that is behaving in a similarly odd manner all of a sudden, which has never happened before. Though now I think about it, I did copy files to new hard drives 'cos I changed 2 hard drives in that computer. In which case I could delete the backup recreate it, and the problem won't recur. – barlop – 2013-04-28T13:52:48.650
@AlwaysLearning but I might dig a bit (or a lot if i'm nuts) just to figure out what is going on in more detail 'cos that often helps for the future. – barlop – 2013-04-28T13:55:56.490
