UltraCompare feature highlights

• Themes：
• Whether you prefer a darker look, or a more classic white-based skin, UltraCompare's interface is completely themeable, and comes with several themes hand crafted at IDM. If you design a theme you'd like to share with the rest of our users, send us a pull request on GitHub, or simply email it to our support team.
•  
• Compare over FTP：
• UltraCompare's powerful compare functions work just as well over FTP, and even network shares and connected drives. Simply click to open from FTP, choose your connection or create a new one to save for future use. It's perfect for quickly checking local files and folders against what's already on the server.
•  

• Word/Excel/PDF Compare：

  UltraCompare's special document handling makes it easy to compare Word and PDF files. Just open them in your session as you would any other file, and let us take care of the rest.
•  
• Zip/Rar/Jar compare：
• Sometimes you simply want to quickly compare the contents of a file archive without extracting it for a normal file or folder compare. We've got you covered. With UltraCompare, you can easily open and compare .zip, .rar and .jar files. No setup required.
