vimdiff - can edit two or three versions of a file with Vim.

syntax vimdiff file1 file2 [file3]

syntax gvimdiff file1 file2 [file3]
or
syntax vim -d file1 file2

Vimdiff starts Vim on two (or three) files. file three is optional.

When you compare them manually, you might make a mistake, and it's easy to miss minute changes. Apart from that, finding changes in large files can be exhausting.

Each file gets its own window. The differences between the files are highlighted. This is a nice way to inspect changes and to move changes from one version to another version of the same file. and same as the gvim window also.

in each window the 'diff' option will be set, which causes the differences to be highlighted.
