Hi all,

I have a NAS drive with a Pictures folder on it and i also have the same folder on my main pc, What i am looking for is a software that will only copy the new files from NAS folder to the other folder.

Anyone got any idea's which software will do this?
 
robocopy /e "c:\my folder\subfolder" "\\nasdevice\folder\subfolder"

robocopy is part of vista, if you're on xp, then drop this into c:\windows\system32

some nas devices won't work with this type of software, becuase they write their own stupid file time stamps, which is another reason why NAS suck

What a cool bit of software, Im impressed, It's also pretty speedy, Thanks.

Although does the /E tell it to copy only new files or will it copy everything? also will it look in subdirectories?

does it work ok with your NAS?

with some models it will keep overwriting the files because the times are a few seconds out....

there are many more options for using it..

/MIR will delete anything from the destination that has been remvoed from the source

you probably know this, but robocopy /? will give you all the options -can set it to ignore certain folders/files/filetypes




microsoft make it, only takes about 30 seconds to compare my 50gb music folders over a 1gb network :)
 
It seems to be working with my NAS, but it is still doing it and will probably take a while, It is not going to be deleting the files is it? only adding the new files on one folder to the other?
 
robocopy /e "c:\folder" "d:\folder"

/e will only copy files from c -> d.


it won't remove any thing from c or d.


it will only copy from c to d if they don't exist on d, or if the ones on c have been updated (ie, saved) since the copy of d.

This normally happens when you're copying from an NTFS volume (where the filesystem has a 100 nsec timestamp granularity) across to a Samba share on a *nix-based device (where the timestamp granularity is 1 sec).

You should be able to fix it by using Robocopy's /FFT switch, which forces FAT file stamps with a 2-sec granularity, although I've found it still sometimes doesn't work, for reasons I'm not entirely clear about.
