DiffVue is a diff tool, also known as a diff utility for Windows XP and Windows 7, and it lets users compare folders and files as well as ftp site's files against the local files by displaying differences visually.

DiffVue V4.5 contains 4 main applications; DiffVue (a main application to compare your local folders and files), DiffFTP (another main application for FTP), DiffEditor (a visual text editor), and FullVue (a viewer for non-text files).

Screenshots for each application are available in DiffVue Software's website diffvue.com/gallery.
The unique features that DiffVue V4.4.3 comparing to other diff utility software are,
- DiffVue recognizes and displays not only the regular text files but also the binary files such as word-processor, spread sheet, presentation documents or even graphics and CAD files.
- DiffVue offers a PDF file rendition not only from any single file but also from the existing folder so that its bookmark pane looks like a folder tree.

- DiffVue offers a set of localization (L10N) tools. For example, detecting any mal-formatted or missing resource strings during L10N process, e.g. translation for foreign languages used to be L10N engineers' nightmare, but detecting them is part of DiffVue L10N tools. The file extensions of the resource file-format recognized by default are RC/RC2/RESX/MC/MTX/INI/IPS.

- DiffFTP compares users' local files and folders against ones in their FTP server by the file contents, and then transfers files like all commercial FTP software.
