Compare directories on Windows

I copied many many files from one hard drive to another. During the process some of the files where skipped. I now want to find who they where and try to take care of them.

How can I figure out what files are missing from my copy ?


Teracopy is excellent, and it can do that.

Also, it can verify that the files were correctly copied (checksum each end and compare).

It's also a all-around nice replacement/upgrade for the windows copy dialog.


I ended using PathSync


If you are using TotalCommander as your file manager, than there's a "Synchronize Dir..." command that will show you a visual comparison between two directory structures. It is very efficient, and much faster to use than traditional diff software.


You can try Beyond Compare to do the comparison. http://www.scootersoftware.com/

To make the copy, try robocopy and keep a logfile. It gives clear output what has been skipped.


I've had some success with Microsoft's Sync Toy, it doesn't cope very well with removable drives which are allocated a different drive letter each time they are connected but it might help you:

Microsoft Sync Toy

You would set up a sync partnership between the two different directories and then in theory running the Sync Toy would synchronise the two.


I am using SyncBack - Freeware from 2brightsparks.

When you start the program it pops up with the config for a new task. Select backup and the two folders you want to check. After clicking on run the program checks the differences and shows you a list of all the files. Afterwards you can decide if Syncback should copy the missing files.
