Many times it happen that we need to see the difference in two versions of a file and some other time we need to synchronize (see how two folder differs) two folders.
If you use source control like perforce then you can diff file and see the file difference. Similarly there are other tools which does this stuff.
Eric Sink and his company (
Sourcegear) has made a
Diffmerge utility freely available to all. It support wide variety of characters and it provides folder difference feature too.
This kind of utility is typically used during code review, see the changes from the master file or directory, synchronize two folders and the list goes on.
