Diffinity

If you have to compare large blocks of text, Diffinity will make your work significantly easier. The software can point out any differences between lines and words down to the last letter. Also, the software can show you all the differences in an easy to understand manner and it gives you the possibility of making the texts identical without any effort.

The software is offered completely free of charge, but you can make a donation if you wish to support further developments. It comes in a small package and it can be installed in just a few seconds, on any popular Windows platform. It doesn't ask for any special tools or services and its hardware requirements are modest.

All you have to do is copy and paste two blocks of text or load two documents in separate panes and the software will highlight all differences immediately. Besides highlighting the entire lines where differences are detected, Diffinity also highlights specific words or letters that are present on one pane, but not the other.

The compared texts are displayed side by side and if you scroll on one pane, the other text will scroll automatically. If you spot a difference, you can select the line in question and just click a button to copy the content from one side to the other.

The software provides a good number of customization options as well. You can choose different color themes for the interface and set it to highlight with different colors, set the application to ignore case differences and more. A particularly useful feature is the possibility of integrating Diffinity into the Windows Explorer context menu. This gives you the possibility of loading text files into the left and right panes from a standard explorer window.

Any differences between two text files can be found and eliminated in just a few moments, thanks to Diffinity's efficient functionality.
